All Legal Documents

1. Introduction and Acceptance

These Terms of Service ("Terms") constitute a legally binding agreement between you ("Customer," "you," or "your") and Signa Technologies AS, a company organized under the laws of Norway, with its registered address at Universitetsgata 2, 0164 Oslo ("Signa," "we," "us," or "our").

By accessing or using the Signa API, website (signa.so), documentation, SDKs, or any related services (collectively, the "Service"), you agree to be bound by these Terms. If you are using the Service on behalf of an organization, you represent and warrant that you have the authority to bind that organization to these Terms.

If you do not agree to these Terms, you may not access or use the Service.

2. Description of the Service

Signa provides a trademark intelligence API that enables programmatic access to trademark search, clearance, monitoring, and listing-scanning capabilities across global trademark registries, including but not limited to the USPTO, EUIPO, WIPO, and UKIPO (the "Service").

The Service aggregates, normalizes, and provides access to publicly available trademark data from third-party sources and applies algorithmic and AI-assisted analysis to that data. The Service is designed for integration into software applications, platforms, and workflows by developers and businesses.

3. IMPORTANT DISCLAIMER — NOT LEGAL ADVICE

THE SERVICE IS PROVIDED FOR INFORMATIONAL AND TECHNOLOGICAL PURPOSES ONLY. SIGNA IS A TECHNOLOGY COMPANY, NOT A LAW FIRM. NOTHING PROVIDED THROUGH THE SERVICE CONSTITUTES LEGAL ADVICE, LEGAL OPINION, OR A LEGAL RECOMMENDATION.

3.1 The trademark data, search results, clearance assessments, risk scores, similarity analyses, monitoring alerts, and any other outputs provided by the Service (collectively, "Output") are generated through automated processes, including artificial intelligence and machine learning algorithms. Outputs are inherently probabilistic and may be incomplete, inaccurate, outdated, or otherwise unreliable.

3.2 You acknowledge and agree that:

(a) The Service does not replace the advice, judgment, or services of a qualified trademark attorney or legal professional.

(b) No Output from the Service should be interpreted as a definitive determination of trademark availability, registrability, infringement risk, or legal compliance.

(c) Trademark law is complex, jurisdiction-specific, and subject to interpretation by human examiners, courts, and tribunals. Automated analysis cannot fully replicate this human judgment.

(d) The absence of a conflict identified by the Service does not mean no conflict exists. The Service may fail to identify relevant prior marks, common-law rights, pending applications, or other sources of potential conflict.

(e) You are solely responsible for any decisions made based on the Output, including but not limited to decisions to adopt, use, register, or continue using any trademark, brand name, or product listing.

(f) Signa strongly recommends that you consult a qualified trademark attorney before making any legal or business decisions based on Output from the Service.

3.3 You expressly waive any claim against Signa arising from your reliance on any Output as legal advice or as a substitute for legal counsel.

3.4 Unsuitability for Official Proceedings. The Output is not designed, intended, or suitable for submission to trademark offices, courts, arbitral tribunals, or administrative bodies as evidence of due diligence, prior art searches, or trademark availability. Any official trademark filings, oppositions, or enforcement actions must be prepared and verified independently by qualified legal professionals. Signa accepts no responsibility for any Output used in connection with official proceedings.

3.5 AI-Generated Analysis. Where the Service provides AI-assisted similarity analysis, risk scores, conflict assessments, or clearance recommendations, such outputs are generated by machine learning models that may change over time, may not account for all relevant legal factors, and may produce different results for the same query at different times due to model updates and data changes. You acknowledge that these AI-generated analyses are probabilistic estimates, not deterministic legal conclusions.

4. Account Registration and API Keys

4.1 To access the Service, your organization must create an account and obtain API credentials ("API Key"). You agree to provide accurate, current, and complete registration information and to keep it updated.

4.2 You are solely responsible for maintaining the confidentiality and security of your API Key and organization account credentials. You are responsible for all activity that occurs under your organization's account, whether or not authorized by you.

4.3 You must immediately notify Signa at security@signa.so if you become aware of any unauthorized use of your account or API Key, or any other breach of security.

4.4 Signa reserves the right to suspend or terminate any account or API Key that we reasonably believe has been compromised or is being used in violation of these Terms.

5. Plans, Fees, and Payment

5.1 Free Tier. Signa may offer a free tier of the Service with limited functionality and/or usage limits. The free tier is provided at Signa's sole discretion and may be modified, limited, or discontinued at any time without notice.

5.2 Paid Plans. Paid plans are available with additional features and higher usage limits as described on our pricing page. By subscribing to a paid plan, you agree to pay all applicable fees.

5.5 Overages. If your usage exceeds your plan limits, you may be charged overage fees as described in your plan terms, or your access may be rate-limited or suspended.

5.6 Taxes. All fees are exclusive of taxes. You are responsible for all applicable taxes, including VAT, GST, or sales taxes. Signa will charge applicable Norwegian VAT where required.

5.7 Price Changes. Signa may change its fees upon 30 days' written notice. Your continued use of the Service after a fee change constitutes acceptance of the new fees.

6. Acceptable Use

6.1 You agree to use the Service only for lawful purposes and in compliance with these Terms, all applicable laws, and all applicable regulations.

6.2 You shall not:

(a) Use the Service to engage in, facilitate, or support trademark fraud, bad-faith trademark filings, cybersquatting, or any form of intellectual property abuse.

(b) Systematically scrape, download, or bulk-extract data from the Service for the purpose of creating a competing product or service, or for resale of the data as a standalone dataset.

(c) Attempt to reverse-engineer, decompile, disassemble, or otherwise attempt to derive the source code, algorithms, or models underlying the Service.

(d) Circumvent, disable, or interfere with any security, rate-limiting, authentication, or access-control features of the Service.

(e) Use the Service in any manner that could damage, disable, overburden, or impair the Service or interfere with any other party's use of the Service.

(f) Share, transfer, or sublicense your API Key to any third party without Signa's prior written consent.

(g) Use the Service to provide legal advice or to hold yourself out as providing legal services, unless you are a licensed attorney providing independent legal judgment.

(h) Misrepresent the Output of the Service as constituting legal advice, legal opinion, or a definitive determination of trademark rights.

(i) Use the Service in connection with any activity that violates the rights of any third party, including intellectual property rights, privacy rights, or publicity rights.

6.3 Signa reserves the right to investigate and take appropriate action against any use that violates these Terms, including suspension or termination of access without notice.

7. Intellectual Property

7.1 Signa's IP. The Service, including its software, algorithms, AI/ML models, APIs, documentation, SDKs, user interfaces, trademarks, and trade dress, are and remain the exclusive property of Signa and its licensors. These Terms do not grant you any right, title, or interest in the Service except for the limited right to use the Service in accordance with these Terms.

7.2 Your Data. You retain all rights in the data, queries, and content you submit to the Service ("Customer Data"). You grant Signa a limited, non-exclusive, worldwide license to process Customer Data solely as necessary to provide and improve the Service.

7.3 Aggregated Data. Signa may use aggregated, anonymized, and de-identified data derived from your use of the Service for product improvement, analytics, benchmarking, and research purposes. Such aggregated data will not identify you or any individual.

7.4 Feedback. If you provide Signa with any feedback, suggestions, or ideas regarding the Service ("Feedback"), you grant Signa a perpetual, irrevocable, royalty-free license to use, modify, and incorporate such Feedback without obligation to you.

7.5 Third-Party Data. The trademark data accessible through the Service is sourced from public trademark registries and other third-party sources. Such data is subject to the terms and conditions of the respective sources. Signa does not claim ownership of third-party trademark data.

8. Data Accuracy and Third-Party Sources

8.1 The Service accesses, aggregates, and normalizes trademark data from third-party trademark offices, registries, and public databases. Signa does not control and is not responsible for the accuracy, completeness, timeliness, or availability of such third-party data.

8.2 Trademark registries may contain errors, omissions, delays in updating, or missing records. The Service's database may not reflect the most recent filings, status changes, or office actions at any given time.

8.3 AI-assisted similarity analysis, including fuzzy matching, phonetic analysis, and visual similarity detection, is based on algorithmic models that are inherently imperfect. These models may produce false positives (flagging non-conflicting marks) or false negatives (failing to flag conflicting marks).

8.4 Signa makes commercially reasonable efforts to keep its data current and its algorithms accurate, but does not guarantee and expressly disclaims any warranty regarding the accuracy, completeness, reliability, or fitness of any Output for any particular purpose.

9. AI System Governance and Transparency

9.1 AI-Powered Features. The Service incorporates artificial intelligence and machine learning technologies for trademark similarity matching, risk scoring, phonetic analysis, and related functions. Signa is committed to responsible AI practices and compliance with applicable AI regulations, including the EU Artificial Intelligence Act where applicable.

9.2 Model Transparency. Signa maintains documentation of its AI models, including training methodologies, performance benchmarks, and testing procedures. Signa publishes a Model Version Log at https://signa.so/model-changelog, which documents material algorithm updates, including: (a) version number; (b) effective date; (c) summary of changes; and (d) impact assessment where changes significantly alter search results.

9.3 Explainability. Where technically feasible, the Service provides explanations for AI-generated outputs, including the factors contributing to similarity assessments and risk scores. You may request a detailed technical explanation of any specific Output by contacting support@signa.so.

9.4 Bias and Fairness. Signa conducts regular testing of its AI models to identify and mitigate bias, including with respect to non-Latin scripts, design marks, and marks from underrepresented jurisdictions. Signa does not guarantee the elimination of all bias from algorithmic outputs.

9.5 Model Updates. Signa may update its AI models at any time to improve accuracy, performance, or compliance. Material model updates that may significantly alter search results or risk assessments will be announced via the Model Version Log and, for enterprise customers, via email notification at least 14 days before deployment. You may request a re-evaluation of prior searches under updated models within 30 days of a material update.

10. Service Availability and SLA

10.1 Signa targets 99.9% uptime for the API but does not guarantee uninterrupted or error-free operation of the Service.

10.2 The Service may be temporarily unavailable due to scheduled maintenance (with reasonable advance notice where practicable), emergency maintenance, force majeure events, or circumstances beyond Signa's reasonable control.

10.3 Signa reserves the right to modify, update, or discontinue any feature or aspect of the Service at any time. For material changes that adversely affect existing functionality, Signa will endeavor to provide 30 days' notice.

10.4 Any uptime SLA, service credits, or availability guarantees applicable to enterprise or paid plans will be set forth in a separate service level agreement.

SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES. IN SUCH JURISDICTIONS, THE ABOVE EXCLUSIONS SHALL APPLY TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW.

12. Limitation of Liability

12.1 TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL SIGNA, ITS AFFILIATES, DIRECTORS, OFFICERS, EMPLOYEES, AGENTS, OR LICENSORS BE LIABLE FOR ANY:

REGARDLESS OF THE THEORY OF LIABILITY (CONTRACT, TORT, NEGLIGENCE, STRICT LIABILITY, OR OTHERWISE) AND EVEN IF SIGNA HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

12.2 Aggregate Liability Cap. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, SIGNA'S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR IN CONNECTION WITH THESE TERMS OR THE SERVICE SHALL NOT EXCEED THE GREATER OF: (A) THE TOTAL FEES PAID BY YOU TO SIGNA DURING THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM; OR (B) ONE HUNDRED EUROS (EUR 100).

12.3 Essential Purpose. THE LIMITATIONS IN THIS SECTION SHALL APPLY EVEN IF ANY LIMITED REMEDY FAILS OF ITS ESSENTIAL PURPOSE.

12.6 Consumer Protection. To the extent any Customer qualifies as a "consumer" under the Norwegian Consumer Contracts Act (angrerettloven) or other applicable consumer protection legislation, the limitations of liability in this Section 12 shall apply only to the extent permitted by such legislation.

14. Confidentiality

14.1 Each party agrees to maintain the confidentiality of the other party's Confidential Information.

15.1 Term. These Terms are effective upon your first access to or use of the Service and continue until terminated.

15.2 Termination by You. You may terminate your account at any time by contacting us at support@signa.so or through your account settings. Termination does not entitle you to a refund of any prepaid fees, except as required by applicable law.

15.3 Termination by Signa. Signa may suspend or terminate your access to the Service at any time, with or without cause, with or without notice. Signa will endeavor to provide reasonable notice where practicable, except in cases of breach, fraud, or conduct harmful to Signa or third parties.

16. Governing Law and Dispute Resolution

16.1 Governing Law. These Terms shall be governed by and construed in accordance with the laws of the Kingdom of Norway, without regard to its conflict of law provisions.

16.2 Jurisdiction. Any disputes arising out of or in connection with these Terms shall be submitted to the exclusive jurisdiction of the Oslo District Court (Oslo tingrett), Norway.

16.3 Pre-Litigation Resolution. Before initiating any legal proceedings, the parties shall attempt in good faith to resolve any dispute through negotiation for a period of at least 30 days.

16.4 Injunctive Relief. Nothing in this section shall prevent either party from seeking injunctive or other equitable relief in any court of competent jurisdiction to prevent irreparable harm.

17. General Provisions

17.1 Modifications. Signa reserves the right to modify these Terms at any time. Material changes will be communicated via email to the address associated with your account or through the Service at least 30 days before they take effect. Your continued use of the Service after the effective date of any modification constitutes acceptance of the modified Terms. If you do not agree to the modified Terms, your sole remedy is to terminate your account.

17.2 Severability. If any provision of these Terms is held invalid, illegal, or unenforceable, the remaining provisions shall continue in full force and effect. The invalid provision shall be modified to the minimum extent necessary to make it valid and enforceable while preserving the parties' original intent.

17.3 Entire Agreement. These Terms, together with the Privacy Policy and any applicable order forms or service level agreements, constitute the entire agreement between you and Signa with respect to the Service and supersede all prior or contemporaneous agreements.

17.4 No Waiver. Signa's failure to enforce any provision of these Terms shall not constitute a waiver of that provision or any other provision.

For the avoidance of doubt, the Service relies on data feeds from third-party trademark offices, which may experience outages, delays, or errors outside Signa's control. Customers are responsible for independently verifying critical trademark information directly with official registries, particularly for time-sensitive matters such as opposition deadlines.
