Patentcloud

Patentcloud is a patent analytics and search platform built by InQuartik Corporation of Taiwan for IP professionals, patent counsel, brokers and analysts. It is sold as six applications sharing one patent database: Patent Search, Design Search, Patent Vault, Due Diligence, Quality Insights and SEP OmniLytics. Quality Insights assesses the validity and quality of a US patent in one click, pulling file wrappers and generating prior art comparisons.

Its Semantic Prior Art function uses the vendor's own machine learning to return up to 300 references from six patent authorities, ranked by semantic similarity. A generative AI Patent Summary feature condenses each reference and highlights terms that align with the claims at issue. Design Search matches design patents from an uploaded image, and Patent Vault is a shared workspace for up to 100,000 patents and twenty collaborators.

Products are sold individually or in five bundled plans, billed monthly or annually by credit card, with free trials. InQuartik is ISO 27001 certified across all six applications and hosts data with Amazon Web Services in Oregon and Tokyo and Taiwan Mobile in Taipei. The terms are governed by the law of the Republic of China, with disputes heard in the Taipei District Court.

BB on AI CentralityThe models are the engine of a core capability, layered on a product that would still function without them as a document or workflow system.

AI Centrality

How much of the product is actually AI. Whether the machine learning is the mechanism the buyer is paying for or a feature layered onto conventional software, and whether the vendor is specific about which is which.

A curated global patent database, Patent Search as a Boolean and bibliographic research tool, and Patent Vault as a portfolio workspace holding up to 100,000 patents with folders, projects and up to twenty collaborators would all work without the models. Semantic Prior Art runs on the vendor's own machine learning to predict relationships between a patent and potential prior art and return ranked references across six jurisdictions.

A generative AI Patent Summary condenses each reference and highlights terms that align with the claims at issue; it reached Due Diligence in June 2023, Quality Insights in October 2023 and Patent Vault in February 2024. Design Search matches design patents from an uploaded image, and Quality Insights generates prior art references automatically with a calculated claim disclosure rate. The platform is sold as six applications that can be bought separately, and several do not depend on the models. InQuartik's own framing puts high quality patent data first and analytics over it second.

BB on Citation Accuracy and Hallucination DisclosureGrounding is real and documented, with linked primary sources and a described retrieval method, short of published accuracy figures an outsider can test.

Citation Accuracy and Hallucination Disclosure

Whether the vendor publishes measured accuracy on citations and assertions, grounds output to primary sources, and says plainly what its system does when it does not know. Legal has a documented public record of fabricated citations reaching filed briefs, so an untested claim of accuracy is not evidence.

Every output a user acts on is a patent document that can be opened and checked. Semantic Prior Art returns up to 300 references from six patent authorities. Quality Insights surfaces file wrappers and supports claim construction, and Prior Art Analytics compares references against the claims at issue and calculates the share of claim elements already disclosed. References are ranked by relevance and starred where semantic similarity exceeds the overall average similarity between all patents and their family members and section 102 prior art. A post about a model upgrade reports a pairing success rate for novelty prior art rising from 77 to 86 percent, with the error rate down 40 percent, and marketing claims prior art search time cut by over 50 percent.

Those figures measure an internal classification improvement on two third party portfolios rather than the accuracy of the product's output. No failure modes are named. Clause 11 disclaims liability for errors or omissions and places that risk on the client.

Source: Vendor Published
CC on Autonomy and Oversight ModelAutonomy is claimed and oversight is asserted without a mechanism. Human in the loop appears as a phrase rather than a described control.

Autonomy and Oversight Model

What the system decides on its own, what a lawyer must approve, and whether the vendor documents where the review point sits. A tool that drafts under review and a tool that files without one are different products and different risks.

Clause 11 of the Terms of Use states that no legal advice is intended or offered, that the vendor disclaims all liability for any decision taken in reliance on the content, and that the client assumes the risk of possible errors or omissions. That allocates responsibility and says nothing about how the system is supervised. No published material describes what the system does unaided, what constrains it, what review surface a professional works through, or how an output returns to human judgment, and no mode or setting is documented.

The starred relevance threshold on Semantic Prior Art tells a reviewer which references exceed average semantic similarity, a single indicator a professional can act on. The platform retrieves, ranks and summarizes patent documents for a professional to assess rather than drafting or acting on a matter.

Source: Vendor Published
CC on Operational and Outcome EvidenceCustomer logos and unattributed testimonials stand in for evidence, or results are quoted with no basis stated.

Operational and Outcome Evidence

Named, dated evidence that the product works in production at real firms or legal departments. Case studies with figures and identified customers count. Unattributed testimonials and launch announcements do not.

A post about a model upgrade reports the pairing success rate for novelty prior art on an Nvidia portfolio rising from 77 to 86 percent, with a 40 percent cut in the error rate, and works through a second example on a Masimo portfolio. Marketing claims prior art search time cut by over 50 percent. Those examples name the portfolios analyzed, not customers who deployed the product, so they show the tool working on public patent data rather than use by a buyer.

The About page adds more than 440,000 patents handled over 35 years, which describes leadership experience rather than deployment. No named customer, case study or attributed testimonial appears in InQuartik's blog or About page, or in coverage of the company.

Source: Vendor Published
CC on Privilege and Confidentiality PostureConfidentiality is asserted in general terms, or the commitment lives only in a sales conversation and cannot be read in advance.

Privilege and Confidentiality Posture

How client confidences are handled: attorney client privilege and work product treatment, segregation of one client matter from another, whether client data trains any model, and what the vendor commits to in writing rather than in marketing.

Section 9 of the Terms of Use binds both parties to hold confidential the contents, terms and all information related to the Agreement for ten years after termination. That protects the deal, not the client's matter material. Nothing in the Terms commits InQuartik to hold in confidence the searches a client runs, the portfolios it assembles, the notes it takes or the reports it generates. Elsewhere the vendor publishes a security posture, not a confidentiality commitment.

Three clauses concern the client's search activity, which for a patent professional can itself be privileged work product. Clause 3.2 records that the vendor collects the client's searches, browsing history, notes and other platform activity, clause 3.11 adds the terms, phrases and choices made while searching, and clause 3.4 reserves the right to analyze and compile statistics from that information to improve services and develop new ones.

Privilege and work product are not addressed. No position is stated on what any model provider may retain, none being named.

Source: Vendor Published
BB on UPL and Professional Responsibility PostureA real position is published on advice versus tooling, short of full treatment: commonly a disclaimer without the supervision and competence dimension, or silence on jurisdiction limits.

UPL and Professional Responsibility Posture

Whether the vendor is clear that it supplies a tool rather than legal advice, who its audience is, and how it addresses unauthorized practice of law, competence and supervision duties, and jurisdiction limits. ABA Formal Opinion 512 is the reference point. Where the advice line is not the duty a product raises, the axis is read through the nearest professional duty it does raise: judicial conduct rules and the reviewing duty for products sold only to courts, and the duty to bill for time actually spent for products that draft time entries.

Clause 11 of the Terms of Use, the customer agreement, states that no legal advice is intended or offered by InQuartik in making any of the content available, and that the vendor disclaims all liability for any decision taken by any party in reliance on the content. The surrounding sentence adds that the client assumes the risk of possible errors or omissions, so the allocation is explicit. The vendor names IP professionals, attorneys, patent counsel, brokers and analysts as its audience, and clause 5.5 contemplates institutional subscriptions for law firms, corporations and government entities, so this is a professional tool sold to professionals rather than a consumer product.

Nothing addresses how the product supports a practitioner's competence or supervision duties, and no jurisdiction limit is named, despite a database spanning six patent jurisdictions and validity analysis built for US patents.

DD on AI Governance and Bias DisclosureNo governance position published for a system whose output affects legal outcomes.

AI Governance and Bias Disclosure

Published governance over model behavior: who owns it inside the vendor, what is tested before release, and what is disclosed about disparate output across matter types, parties, or populations.

No governance position is published for a system whose output informs patent validity and freedom to operate decisions. Nothing identifies who inside the vendor is accountable for the models, no testing regime before release is described as governance, no policy or principles statement exists, and no certification such as ISO 42001 is claimed. Nothing addresses uneven output across jurisdictions, technology fields, filing languages or portfolio sizes, which is where bias would matter on a patent analytics product.

A post about a model upgrade does publish a before and after evaluation of classification performance on two named portfolios. That is measurement, not a governance framework, an accountability structure or a testing regime that could be audited. The ISO 27001 certification covers information security management.

Source: Vendor Published
CC on AI Safety and Data StewardshipA generic privacy policy covers the product without addressing what happens to documents and prompts after processing.

AI Safety and Data Stewardship

Retention, deletion, access control, and what happens to prompts and documents after they are processed. Whether the vendor states its subprocessors and its incident practice, or leaves the buyer to assume.

Clause 3.7 lets the client request export, update, correction or deletion of personal information and require the vendor to stop collecting, processing and using it, with a commitment to comply in a timely manner. Clause 3.8 commits to systematic deletion of identity documents once identity is confirmed. Clause 3.5 requires third party processors to comply with data protection regulation, and clause 3.6 acknowledges transfer across borders with security safeguards.

Access control and infrastructure protection sit inside the ISO 27001 scope. No retention period is stated for searches, notes, projects or generated reports, and clause 3.1 says instead that the vendor may at all times receive and store such information. Nothing describes what happens to a client's Patent Vault projects on termination; clause 9.4 covers return or destruction of confidential information, which section 9 defines as the agreement's own terms.

No subprocessor is named, clause 3.5 referring only to trusted third party processors and service providers. No incident or breach notification practice is published.

Source: Vendor Published
CC on AI Liability and RecourseLiability is addressed only through a standard limitation clause that disclaims the exposure the product creates.

AI Liability and Recourse

What the vendor stands behind contractually when its output is wrong. Indemnities, caps, carve outs, insurance, and whether any of it is published or only reachable through a negotiated agreement.

Clause 11 disclaims liability for errors or omissions throughout the services, states that the client assumes that risk as a subscriber, and disclaims all liability for any decision taken by any party in reliance on the content. Clause 15 is the only indemnification article. It obliges the client to indemnify, defend and hold harmless InQuartik under five heads, including breach, third party IP claims arising from client submissions, and the client's activities in connection with the database and reports.

There is no vendor indemnity of any kind. The warranties at clause 10.1 are corporate rather than performance warranties: that the services contain no libelous matter, that the vendor operates lawfully and holds necessary permits, and that it has capacity to contract. Nothing warrants the accuracy, completeness or fitness of the analysis, and no insurance is referenced. Section 12 is headed Limitation of Liability, Cap and Force Majeure.

Source: Vendor Published
DD on Practice Systems Integration DepthNo integration into practice systems located, or the product stands alone and requires work to move to it.

Practice Systems Integration Depth

How deeply the product reaches into the systems legal work already lives in: document management such as iManage and NetDocuments, Word and Outlook, contract lifecycle management, matter management, e-billing, and court filing systems.

No integration into practice systems is published, and the vendor's own position is that none is needed. The bundle FAQ states that the plans let a team work on the Patentcloud platform without introducing additional third party tools, a claim that the platform stands alone rather than a claim of interoperability. No docketing system, document management system, IP management platform or patent office filing interface is named as a connection, no API is documented or referenced, and no integrations page is listed.

Export and sharing exist inside the platform's own boundary. PatentMatrix dashboards and Due Diligence and Quality Insights reports can be shared with colleagues and partners, and the KEEP function saves findings into a Patent Vault project for team members. Those move work between the vendor's own applications and users, not into the systems a firm already runs.

Source: Vendor Published
BB on Deployment Model and Data ResidencyDeployment model is stated clearly with partial residency detail, or residency is offered without the processing location being addressed, or the tenancy model is stated on its own with no residency detail published.

Deployment Model and Data Residency

Where the software runs and where the data sits. Multi tenant cloud, single tenant, private deployment, on premises, and whether region of residence is a published option or an enterprise conversation.

The platform runs on a hybrid cloud infrastructure in named locations: Amazon Web Services data centers in Oregon and Tokyo and Taiwan Mobile data centers in Taipei. The vendor states the AWS facilities are certified to ISO 27001, PCI DSS Service Provider Level 1 and SOC 2, and that the Taipei facilities carry Tier III certification in design, facility and operations. Physical and environmental security sits inside the ISO 27001 scope.

No tenancy model is stated, so whether the deployment is single tenant or multi tenant and how customers are separated is not known. Processing location is not distinguished from storage location, and which site runs the analysis is not stated. No region choice is offered. The geography is the vendor's architecture rather than a customer election, and clause 3.6 confirms that information collected in one jurisdiction may be moved to servers in another under unspecified safeguards.

AA on Security Certifications and Trust CenterCurrent independent attestation with named scope, reachable without a sales call: a trust center carrying reports, dates and the standards actually covered.

Security Certifications and Trust Center

Independent attestation a buyer can pull without a sales call: SOC 2, ISO 27001, penetration test summaries, a trust center with current reports and named scope rather than a badge image.

InQuartik's Trust and Security page states that InQuartik is ISO 27001 certified and sets out the scope: all six Patentcloud applications listed individually, Quality Insights, Due Diligence, SEP OmniLytics, Patent Search, Design Search and Patent Vault, together with internal systems covering development, maintenance, physical security, and the management of application systems, data protection systems and network communications.

The certificate is offered for direct download rather than through an account executive or an NDA. The page also names the hosting estate and the certifications those facilities hold. The latest certification announcement is a renewal in the second year rather than a confirmation for the current year. No SOC 2 report of the vendor's own is claimed; the SOC 2 reference belongs to AWS and its infrastructure.

Source: Vendor Published
CC on Model Supply Chain DisclosureThe vendor refers to advanced or proprietary models without identifying what sits underneath.

Model Supply Chain Disclosure

Which models sit underneath, whose they are, where they run, and whether the vendor commits to telling customers when that changes. A legal buyer inherits every dependency it cannot see.

Semantic Prior Art is described as powered by Patentcloud's machine learning technology, a claim of ownership rather than an identification. The Patent Summary feature is described as generative AI without naming a model, a provider or an architecture, and a model upgrade is discussed in terms of classification performance without saying what was upgraded. No foundation model or model provider is named anywhere, and nothing states whether the generative component, which sends patent text to a model, is built in house or supplied by a third party.

The Terms of Use are silent on the point. Amazon Web Services and Taiwan Mobile are named, but as infrastructure: naming a cloud host says where a model runs, not whose model it is. The vendor does disclose that machine learning and generative AI sit behind named features. Nothing is named that a change notice could cover.

BB on Commercial TransparencyReal pricing is published for part of the range, with enterprise tiers withheld, or the unit and structure are stated without the figure.

Commercial Transparency

Whether a buyer can learn what this costs without entering a sales process: published rates, the unit being charged, what sits behind an enterprise tier, and what implementation adds.

Five bundle plans are named: Premium, Patent Due Diligence, Patent Portfolio Analysis, Patent Litigation and Freedom to Operate, each built around a stated patent scenario with a feature comparison table showing what it includes and excludes. Separate pricing pages exist for the individual products. The unit of charge is one account per plan, with additional seats on request. Entitlements are quantified: storage for 100,000 patents, up to 1,000 customizable folders and up to twenty collaborators.

The bundle discount is stated as up to 79 percent against standalone subscription. Billing is monthly or annual, charged automatically to a credit card at the start of each cycle, and plan changes and cancellations take effect from the next cycle. Free trials include seven day trials and two free validity analysis reports. Custom bundles and additional seats go through a sales conversation. Plan figures are displayed in the comparison tables on the pricing pages.

Source: Vendor Published
BB on Firm and Practice CoverageSegment and practice coverage is described with substance, short of the boundaries: what is supported is clear, what is not is left open.

Firm and Practice Coverage

Who the product is actually built for. AmLaw, midlaw, small firm and solo, in house departments, government and courts, and which practice areas are supported rather than merely claimed.

The buyer segments are named individually: IP professionals, attorneys, dealers, brokers, scientists, engineers, financiers and designers, and clause 5.5 of the Terms contemplates institutional subscriptions for law firms, corporations and business, charitable or government entities. The five bundle plans are named practice scenarios, each mapped to the work it supports: due diligence before buying or licensing, portfolio analysis at any scale, litigation response by finding weaknesses in the patent at issue, freedom to operate by clearing products in target markets, and an enterprise plan covering every scenario.

A dedicated application serves standard essential patent work, naming 5G and 6G claim charting and FRAND issues, and another serves design patent clearance. US, European, Japanese, Chinese, Korean and WIPO documents are named as the semantic prior art scope. The limits are not stated. Nothing says which jurisdictions fall outside coverage, and the validity and file wrapper analysis in Quality Insights is described for US patents without saying what is unavailable elsewhere.

Pricing

No published figure

  • Patentcloud is sold as six products, available on their own or in one of five bundles built around common patent jobs: due diligence, portfolio analysis, litigation, freedom to operate, and a Premium plan covering every scenario. Bundling is where the discount is, up to 79 percent against buying the same products separately. Each plan is one account, billed monthly or annually to a credit card, and every bundle includes Patent Vault with storage for 100,000 patents, up to 1,000 folders and up to 20 collaborators. Free trials are available, including two free validity reports on Quality Insights. Extra seats, more storage or a different product combination are quoted individually.

Five named bundles are published with the unit of charge stated. The plans are Premium, the plan for enterprise teams covering every scenario, Patent Due Diligence, Patent Portfolio Analysis, Patent Litigation and Freedom to Operate. Standalone pricing pages exist for Patent Search, Design Search, Patent Vault, Due Diligence and Quality Insights. The unit of charge is one account per plan, with more seats on request.

Entitlements include storage for 100,000 patents, up to 1,000 folders and up to 20 collaborators per account. Monthly or annual billing is charged to a card at the start of each cycle, and the bundle discount is up to 79 percent against standalone subscription. Free trials include seven day trials and two free Quality Insights validity reports. The agreement sets payment within thirty days of invoice, charges that are not refundable once a subscription starts, automatic renewal for twelve month periods unless ninety days notice is given, and no termination for convenience in the first twelve months. Plan figures are displayed in the comparison table on the pricing pages.

Legal Signals

What each signal means

A signal records what public sources say on the date shown. It is not a grade and it is not a recommendation. Where a signal reads Not addressed, it means the index did not locate the material in public sources on that date, which is a statement about disclosure rather than about the product.

Confidentiality and Privilege

Client Data in Training

Can material a lawyer puts into this product be used to train a model?

Terms silent

A published agreement or policy exists and none of it addresses the question either way, or the document that would answer it could not be read and the summary names the retrieval limit. The summary states which shape the silence takes: an improvement right granted that never names training, or no improvement right granted at all.

No provision of the published agreement addresses training, model improvement or machine learning. The Terms of Use, last updated 1 May 2022, run to twenty one articles, and none mentions the models the product ships, though the vendor describes Semantic Prior Art as running on its own machine learning and Patent Summary as generative AI. The quoted clause is the closest. It permits analysis and statistical compilation to improve and develop services, and names neither training nor machine learning.

Its subject matter is broader than a typical usage statistics clause. Clause 3.2 says the vendor collects the client's searches and browsing history, notes and other platform activity, and clause 3.11 adds the terms, phrases and choices made while searching. What may be analyzed under the quoted clause therefore includes a patent professional's search strategy and working notes, not telemetry alone. Clause 3.4 also permits sharing analysis or statistics publicly or with third parties in aggregated form that does not identify individuals. Nothing published states that client material is not used to train.

Prompt and Output Retention

How long does the product keep what a lawyer typed, and can that be set to zero?

Disclosed without a period

Retention is acknowledged in public materials with no stated period.

The agreement says material is stored and does not say for how long. The quoted clause says the vendor may at all times receive and store usage information. Clauses 3.2 and 3.11 list what is stored: IP address, software and hardware attributes, searches and browsing history, the client's notes, and the terms, phrases and choices made while searching, configuring alerts or bookmarking. No retention schedule, deletion cycle or maximum period appears in the Terms of Use or the privacy policy, and nothing gives the client a retention setting.

The client does have a route by request over personal information rather than over the work. Clause 3.7 lets the client require export, update, correction or deletion of personally identifiable information and require the vendor to stop collecting, processing and using it, with a commitment to comply in a timely manner, though the vendor may charge a reasonable cost. Clause 3.8 commits to deleting any identity document once identity is confirmed. Nothing addresses what becomes of Patent Vault projects, saved reports or search history on termination.

Ethical Walls and Matter Segregation

Does retrieval respect the firm’s ethical walls, or can the model read across them?

Own model, documented

The product maintains its own permission model, documented, requiring the firm to keep it aligned.

Patent Vault organizes work into projects with customizable folders and up to twenty collaborators per account. Project members must be authorized to edit before they can save findings into a shared project through the KEEP function, and reports and dashboards are shared deliberately with named colleagues rather than being open by default. The quoted clause restricts an institutional subscription to individuals designated as subscribers at purchase, so access is by named user rather than open to the whole firm.

The firm configures and maintains that permission structure, which is a collaboration model rather than a segregation mechanism. Nothing addresses walls between matters or between a firm's clients inside one account, nothing describes what stops a colleague on one engagement seeing work saved from another, and no conflicts or screening capability is published. The product holds its own repository and searches a public patent database rather than a customer document system, so there is no source access model to inherit.

Third Party Request and Subpoena Notice

If someone subpoenas the vendor for a firm’s data, does the firm hear about it first?

Disclosure addressed, notice absent

Published terms or policy address disclosure to authorities or in response to legal process, and no commitment or reservation regarding customer notice is located anywhere. The vendor has told the customer that data can leave and has said nothing about whether the customer hears of it.

Compelled disclosure is addressed and notice is not mentioned. Clause 9.1.2 carves compelled disclosure out of the confidentiality obligation on the quoted terms, and clause 9.1.3 adds an exception for disclosure required in connection with litigation, arbitration or administrative or other investigations and proceedings. Both permit disclosure, and neither commits the disclosing party to tell the other in advance, to give it a chance to seek a protective order, or to notify it afterwards.

Disclosure is limited to the extent of the legal obligation, which constrains scope but is not notice. Clause 14.6 states that InQuartik may cooperate with legal authorities and third parties in investigating any suspected or alleged crime or civil wrongdoing, again with no notice commitment. The terms do not reserve discretion over notice either; they do not reach the question. Section 9 defines the confidential information it protects as the contents, terms and information related to the Agreement, so the client's searches, projects and notes are not obviously covered by the article that contains these exceptions.

Accuracy and Authority

Primary Law Corpus Provenance

Where does the law in this product come from, and does the vendor have the right to use it?

Jurisdictions only

Coverage is described by jurisdiction with no identification of the underlying corpus.

Coverage is described by jurisdiction, and the source of the underlying data is not identified. Semantic Prior Art returns US, European, Japanese, Chinese, Korean and WIPO documents, Quality Insights validity analysis is described against US patents, and the platform is presented as holding global patent data. No data supplier, feed, national office agreement or open data source is named, no update schedule or currency date is published, and no license or rights basis is stated for any part of the database.

The nearest the terms come is clause 2.5, which excludes from the vendor's service commitments any restrictions imposed by the database source, such as a jurisdiction's patent office, naming a category of source without identifying one. Clause 5.7 asserts that all right, title and interest in the Database and the Content belong exclusively to InQuartik and bars the client from mining it or building a searchable database from it, which asserts the vendor's rights downstream without addressing how the underlying records were obtained.

Good Law Verification

Does the product tell you when the authority it just cited has been overruled?

Own treatment signal

The vendor computes and surfaces subsequent history itself, with the method described.

For a patent rather than a case, whether an authority still stands is a question of validity and legal status, and Patentcloud computes that itself. Quality Insights is described as a one click solution giving consolidated data to evaluate the validity and quality of a US patent, surfacing file wrappers, supporting claim construction and generating prior art comparisons. It generates prior art references that bear on validity, and Prior Art Analytics compares references against the claims of the patent at issue and calculates the share of claim elements already disclosed in the file wrapper.

A semantic similarity ranking stars references above a threshold defined against the average similarity between all patents and their family members and section 102 prior art. The method is only partly described. No third party citator or commercial treatment service is named; the computation is the vendor's own, and the product performs the analysis rather than telling the user to check elsewhere.

Source: Vendor PublishedAs of Sep 8, 2026Evidence

Refusal and Uncertainty Behavior

What does the product do when the answer is not in the corpus?

Confidence signal only

The product exposes a confidence or grounding score without an explicit abstention path.

Semantic Prior Art ranks every reference it returns by relevance between the patent at issue and the abstract and first claims of the reference. It stars references whose semantic similarity exceeds the overall average similarity between all patents and their family members and section 102 prior art, and the user can narrow the search by adding selected claim text or keywords. Nothing describes what the product does when it cannot ground a result.

It does not say what a user sees when no reference passes the threshold, whether an empty or weak result is distinguished from a failed search, or what happens where coverage in a jurisdiction is thin. No path for declining to answer is documented. The agreement addresses the same ground only by allocating risk, with clause 11 stating that the client assumes the risk of possible errors or omissions, which is a disclaimer rather than a description of behavior.

Source: Vendor PublishedAs of Sep 8, 2026Evidence

Fabricated Citation Record

Does a public court record exist addressing fabricated or hallucinated legal citations in output from this product?

None located

No court order, opinion or disciplinary record addressing fabricated or hallucinated legal citations produced by this product has been located as of the date shown. This is a statement about the public record on that one subject, not a finding about the product, and this signal is not a litigation history.

The AI Hallucination Cases database maintained by Damien Charlotin records no case naming Patentcloud or InQuartik, and general search returns no filing, sanction, order or judicial finding involving either. The product does not draft legal argument or generate citations to case law. It retrieves patent documents from a database and ranks and summarizes them, and every reference it surfaces is a real patent record the user can open, though the generative Patent Summary feature does produce synthesized descriptions of those documents. This is a statement about the public record rather than a finding about the product.

Professional Responsibility

Bar Guidance Alignment

Has the vendor engaged in public with the ethics opinions its buyers are bound by?

Generic reference

Public materials refer to professional responsibility in general terms without naming guidance.

Clause 11 of the agreement states in the quoted terms that no legal advice is intended or offered. It adds that the vendor disclaims all liability for any decision taken by any party in reliance on the content, and that the client, as a subscriber, assumes the risk of possible errors or omissions. The product is sold to patent attorneys whose validity analysis informs opinions. No named authority appears. No bar ethics opinion is cited, no guidance from a patent bar or an office of enrollment and discipline is discussed, no regulator is named, and nothing maps the product against the professional conduct obligations of the practitioners it is sold to in any jurisdiction. The disclaimer sits in terms last updated in May 2022.

Source: Vendor PublishedNo legal advice is intended or offered by InQuartik in making any of the Content available.As of Sep 8, 2026Evidence

Billing and Fee Posture

Does the vendor address what happens to the bill when the work takes an hour instead of six?

Savings claims only

Public materials claim time savings without addressing billing or disclosure, and the product sits inside a fee relationship between a lawyer and a client where those savings would change the bill.

The savings claims are quantified and aimed at cost. Prior art search time is said to fall by over 50 percent, and the pitch is that a user will never again collect patent data by hand or outsource a prior art search, a claim about displacing outside spend. The bundle material adds savings of up to 79 percent against standalone subscription, a pricing discount rather than a claim about matter economics. Nothing addresses what happens to the bill when a task that took six hours takes one.

No record of AI assisted work is produced for each matter, nothing exists that a firm could show a client about what the analytics contributed, and no guidance on fee or disclosure treatment is published. The buyer may be a corporate IP department, a law firm or a broker, and the claim about displacing outside counsel is addressed to the client side.

Source: Vendor PublishedAs of Sep 8, 2026Evidence

Outside Counsel Guideline Readiness

Can a firm get this vendor through a client’s AI clause without a bespoke negotiation?

Not addressed

No located public material supports a client side disclosure obligation.

No subprocessor list is published, and nothing suggests one is available on request. The quoted clause refers only to trusted third party processors and service providers as a category, committing that they will protect the information and comply with data protection regulation, and names no party. No statement identifies which model providers, if any, see client content. No foundation model or provider is named anywhere, while the vendor describes its machine learning as its own and its Patent Summary feature as generative AI.

Amazon Web Services and Taiwan Mobile are named as data center operators, but naming a host says where a model runs, not whose model it is. Clause 20.1 makes both parties data controllers, so there is no processor relationship, and therefore no data processing addendum, subprocessor annex or disclosure pack for clients.

If a judge’s standing order requires an AI disclosure, can the product produce one?

Not addressed

No located public material addresses court disclosure or verification certification.

No published material addresses court disclosure or certification of verification. Nothing discusses judicial standing orders on AI, no disclosure template or guidance is published, and no export produces a record for each document of the model used, the sources drawn on and the human verification applied. The platform is marketed for patent litigation, with a bundle built around finding weaknesses in a patent at issue, and its claim charts and validity reports are prepared for disputes where an opponent or a tribunal may ask how the analysis was produced.

Reports can be exported and shared, and they list the prior art references relied on, which is a record of sources. Nothing identifies the model used, separates generative Patent Summary output from retrieved document text, or records what a person verified, and nothing describes any of this as serving disclosure. Clause 11 places the risk of errors or omissions on the client without offering anything the client could file.

The AI Legal Index is an editorial reference. It is not a regulatory body, not a law firm, and nothing published here is legal advice or a recommendation to retain or avoid a vendor. Records are verified against published sources, bar guidance and public court records. Where a record reads not addressed, the material was not located in public sources on the date shown. See the Methodology page for evaluation standards and limitations.
