    • Any alleged violation of your local, national, regional, or international data protection, privacy, consumer protection, or other laws
    • Any failure by us to comply with legal obligations imposed by jurisdictions outside the United States
    • Any dispute, controversy, or claim arising under or relating to laws other than those of the United States

  5. Exclusive U.S. Jurisdiction and Law: Notwithstanding your physical location or country of residence, you irrevocably submit to the exclusive jurisdiction of the courts of the State of California and the United States federal courts located in San Francisco County, California, for any and all disputes. You irrevocably consent to personal jurisdiction and venue in such courts.

  6. Waiver of Unknown Claims: You expressly waive the benefits of Section 1542 of the California Civil Code (and any similar provision of law in any other jurisdiction), which states: "A general release does not extend to claims that the creditor or releasing party does not know or suspect to exist in his or her favor at the time of executing the release and that, if known by him or her, would have materially affected his or her settlement with the debtor or released party." You acknowledge that you may later discover claims or facts that are currently unknown or unsuspected, and you nevertheless waive any such claims.

Assumption of All Risk: You voluntarily assume all risks, known and unknown, associated with accessing the Service from outside the United States, including risks related to data protection violations, regulatory penalties, civil liability, criminal liability, or any other consequences arising from such access.

You further agree that any such violations, whether actual or alleged, shall not constitute a breach of these Terms, a breach of any duty owed to you, or grounds for any claim or cause of action whatsoever.

  9. Attorneys' Fees and Costs - Breach-Based Liability: You acknowledge and agree that your access to and use of this Service from outside the United States constitutes a knowing, material, and continuing breach of these Terms. By initiating, maintaining, participating in, or supporting any dispute, claim, lawsuit, arbitration, administrative proceeding, regulatory complaint, governmental investigation, or any other legal or quasi-legal proceeding of any kind against any of the Released Parties (collectively, "Proceedings"), while you are in breach of the geographic restrictions set forth in these Terms, you agree to the following:

    (a) Breach-Based Indemnification: Because your Proceedings arise from, relate to, or are connected with your unauthorized access to the Service from outside the United States—which itself constitutes a material breach—you agree to indemnify, defend, and hold harmless the Released Parties for ALL costs, expenses, damages, losses, and liabilities incurred by the Released Parties in connection with such Proceedings, including but not limited to: (i) attorneys' fees and costs (including fees of multiple counsel if required), (ii) expert witness fees and costs, (iii) court costs and filing fees, (iv) arbitration fees and administrative costs, (v) costs of investigation and discovery, (vi) costs of appeal, and (vii) costs of enforcement of this provision. This indemnification obligation applies regardless of the outcome of such Proceedings, as the obligation arises from your underlying breach, not from the merits of your claims.

    (b) Prevailing Party Fee-Shifting: In addition to and without limiting the breach-based indemnification set forth above, if any Proceedings are resolved in favor of any of the Released Parties (whether by judgment, arbitration award, dismissal, or settlement), you agree to pay all attorneys' fees, costs, and expenses incurred by the prevailing Released Parties, including without limitation costs of appeal and costs of enforcing any judgment or award.

    (c) Liquidated Damages for Unauthorized Access: You further agree that the Released Parties' costs of defending Proceedings brought by users in violation of the geographic restrictions constitute liquidated damages for such breach, as the actual damages are difficult or impossible to calculate. You acknowledge that this liquidated damages provision is reasonable and proportionate to the anticipated harm.

    (d) Joint and Several Liability: If multiple parties bring Proceedings against the Released Parties, and any such parties accessed the Service from outside the United States, such parties shall be jointly and severally liable for all fees, costs, and expenses incurred by the Released Parties.

    (e) No Waiver: Our failure to immediately enforce this provision shall not constitute a waiver of our right to enforce it at any time. We reserve the right to seek payment of all fees, costs, and expenses at any time during or after the conclusion of any Proceedings.

  10. Knowing and Willful Breach: By accessing or using this Service from outside the United States after reading these Terms, you acknowledge that such access constitutes a knowing, willful, intentional, and material breach of these Terms. You agree that this knowing breach may subject you to injunctive relief, specific performance, and monetary damages (including but not limited to the fees and costs described above), and that such remedies may be sought by the Released Parties in any court of competent jurisdiction without the requirement of posting a bond.

  11. Binding Effect: These acknowledgments, waivers, releases, indemnifications, and covenants are binding upon you and your heirs, executors, administrators, successors, assigns, legal representatives, and all persons claiming by, through, or under you.

BY CONTINUING TO ACCESS OR USE THIS SERVICE FROM OUTSIDE THE UNITED STATES, YOU REPRESENT AND WARRANT THAT YOU HAVE CAREFULLY READ, FULLY UNDERSTAND, AND VOLUNTARILY AGREE TO ALL OF THE FOREGOING TERMS. IF YOU DO NOT AGREE, YOU MUST IMMEDIATELY CEASE ALL ACCESS TO AND USE OF THE SERVICE.

Governing Law and Dispute Resolution

Governing Law

These Terms are governed by and construed in accordance with the laws of the State of California, United States, without regard to its conflict of law provisions.

Mandatory Binding Arbitration

PLEASE READ THIS SECTION CAREFULLY. IT AFFECTS YOUR LEGAL RIGHTS, INCLUDING YOUR RIGHT TO FILE A LAWSUIT IN COURT.

Agreement to Arbitrate: You and patentsunset.com agree that any dispute, claim, or controversy arising out of or relating to these Terms, the Service, or your use of the Service (collectively, "Disputes") will be settled by binding arbitration, except that either party may seek injunctive or other equitable relief in court for matters related to intellectual property rights, unauthorized API access, or violations of the Prohibited Uses section.

Arbitration Rules: The arbitration will be conducted by JAMS (Judicial Arbitration and Mediation Services) under its Streamlined Arbitration Rules and Procedures, or if JAMS is unavailable, by the American Arbitration Association (AAA) under its Commercial Arbitration Rules.

Arbitration Location: All arbitration proceedings shall take place in San Francisco, California, or via remote video conference if both parties agree.

Individual Basis Only: You agree that arbitration will be conducted only on an individual basis and not in a class, consolidated, or representative action. You waive any right to participate in a class action lawsuit or class-wide arbitration.

Arbitrator's Authority: The arbitrator may award any relief that a court could award, including attorneys' fees and costs to the prevailing party, but may NOT award relief to anyone other than you individually. The arbitrator's decision is final and binding, with very limited grounds for appeal.

Costs: Each party will pay its own costs and attorneys' fees unless the arbitrator awards them to the prevailing party. If you initiate arbitration, you will pay the filing fee up to $250, and we will pay any additional fees. If we initiate arbitration, we will pay all fees.

Special Provision for International Users: Notwithstanding the foregoing, if you access the Service from outside the United States in violation of our geographic restrictions and initiate arbitration or any other Proceeding against us, you shall be liable for all fees, costs, and expenses as set forth in the "Attorneys' Fees and Costs - Breach-Based Liability" provision in the "Acknowledgment and Waiver by Non-U.S. Users" section, including liability for our defense costs regardless of the outcome of the arbitration or Proceeding.

Small Claims Court: Either party may bring a Dispute in small claims court in San Francisco County, California, if the Dispute qualifies for small claims court and is brought on an individual basis only.

Waiver of Jury Trial

YOU AND PATENTSUNSET.COM WAIVE ANY CONSTITUTIONAL AND STATUTORY RIGHTS TO SUE IN COURT AND HAVE A TRIAL IN FRONT OF A JUDGE OR A JURY. You and we are instead electing to have Disputes resolved by arbitration, except as specified above.

Class Action Waiver

YOU AND PATENTSUNSET.COM AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN YOUR OR ITS INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS OR REPRESENTATIVE PROCEEDING.

If a court or arbitrator determines that this class action waiver is unenforceable, then the arbitration agreement will be void, and the Dispute will be resolved in court subject to the venue provisions below.

Jurisdiction and Venue (If Arbitration Does Not Apply)

If for any reason a Dispute proceeds in court rather than arbitration, you agree that any legal action or proceeding arising out of or relating to these Terms or the Service shall be brought exclusively in the state or federal courts located in San Francisco County, California, and you irrevocably consent to the personal jurisdiction of such courts.

You waive any objection to venue in San Francisco County, California, and any claim that such courts are an inconvenient forum.

Informal Resolution

Before filing a claim for arbitration or in court, you agree to contact us at support@patentsunset.com to attempt to resolve the Dispute informally. We will attempt to resolve Disputes in good faith for at least 30 days before either party may commence arbitration or litigation.

Statute of Limitations

Any Dispute must be filed within one (1) year after the Dispute arises. If you or we do not file within one year, the Dispute is permanently barred.
