Terms of Service

These Terms of Service, together with the documents in §18.1, govern your use of the Pattrans.Ai software and website (the "Service"), operated by PATTRANS COMPANY LIMITED (Tax code 0111399245), Unit 0315, C2 Building, D' Capitale, 119 Tran Duy Hung Street, Yen Hoa Ward, Hanoi, Vietnam ("Pattrans", "we", "us"). By creating an account or completing a purchase after being presented with these Terms, or by otherwise expressly accepting them through the Service, you agree to these Terms and acknowledge that you have been given access to the Privacy Policy. If you accept for an organisation, you confirm you are authorised to bind it.

1. Definitions

• "Service" — the Pattrans.Ai website, applications and AI-assisted translation software.
• "Software" — the Pattrans desktop and web applications.
• "Credits" — prepaid usage units consumed to run translations (§5).
• "Plan" — a subscription or bundle (e.g. a tier) offered by Pattrans.
• "Output" — files the Software generates from documents you submit.
• "Customer Content" — documents you submit and the Output.
• "Merchant of Record" / "Reseller" — a third party that, for certain purchases, is the seller of record and concludes the sale in its own name (§5).
• "Business User" — you use the Service for a trade, profession or organisation. "Consumer" — an individual using it outside any trade or profession.

2. The Service — a software tool

2.1 Pattrans provides AI-assisted translation software for patent and technical documents. You operate the Software: you set terminology, run the translation function, and review the Output.

2.2 Pattrans is a software tool, not a translation or language-services provider. No person reviews your documents or Output for linguistic quality as part of the Service, except that, if you opt in to our quality-improvement programme (described in the Privacy Policy), authorised quality personnel may review your opted-in material internally to improve the Service — this does not give you a human-reviewed, corrected, certified or filing-ready result. We do not otherwise provide human translation, review of translation quality, certification, or legal advice. Limited access to Customer Content may otherwise occur only where necessary for security, technical support you request, incident response, or legal compliance, as described in the Privacy Policy.

2.3 Subject to these Terms, we grant you a limited, non-exclusive, non-transferable licence to use the Software for your own professional, research, organisational or personal purposes, terminable in accordance with these Terms.

3. Eligibility and accounts

3.1 You must be at least 18 and able to form a binding contract.

3.2 You are responsible for the accuracy of your account information and for keeping your credentials secure; you must be authorised to act for any organisation you register.

3.3 You are responsible for activity under your account to the extent resulting from your acts, omissions, or failure to keep your credentials secure. Notify us promptly of any unauthorised use.

3.4 Access may be limited to a number of devices according to your Plan.

4. Acceptable use and restrictions

You agree not to, and not to permit anyone to:

• (a) Unlawful or infringing — use the Service to infringe intellectual-property or other rights, to process content you have no right to submit, or for any unlawful purpose;
• (b) Credits, resale and credentials — resell, sublicense, transfer or exchange Credits or account access, use Credits as stored value or as payment to third parties, or share, pool or distribute credentials to evade user, device or plan limits (authorised personnel within your organisation may use the Service where your Plan permits);
• (c) Payment fraud — make a payment you are not authorised to make, use another person's payment details without authority, submit false or altered payment evidence, falsely claim an overpayment or duplicate payment, manipulate payment confirmation or reconciliation, or initiate a chargeback or payment reversal dishonestly, fraudulently or without a reasonable basis in relation to a charge you authorised and validly incurred (this does not limit your right to dispute an unauthorised, incorrect or legally disputable charge);
• (d) Gaming Credits or promotions — knowingly exploit or manipulate Credits, bonuses, trials, referrals, pricing, counting, cancellation, refund or Credit-release mechanisms, exploit a bug, vulnerability or unintended system behaviour, or create or use multiple or false accounts, coordinated transactions or disposable identities, to obtain benefits you are not entitled to or to evade an eligibility limit or a prior suspension;
• (e) Circumvention and unauthorised access — intentionally bypass or attempt to bypass any security, authentication, access control, rate limit, usage cap or device limit, access another user's account, data or Customer Content without authority, or conduct security testing except under a written programme we authorise;
• (f) Automated or excessive use — access the Service through bots, scripts or other automated means except through interfaces or functionality we provide or expressly authorise, scrape it, or place a load on it beyond the documented limits of your plan or in a manner that materially interferes with the Service or other users;
• (g) Software IP and reverse-engineering — disrupt, overload, reverse-engineer, decompile, or extract or attempt to reconstruct Pattrans's proprietary system models, system dictionaries, prompts, source code or other non-public technical components ("Pattrans Materials"), except to the extent expressly permitted by applicable law notwithstanding this restriction; this does not restrict your use of your own Customer Content, My Termbase or Output;
• (h) Competing use — systematically access or use the Service to extract, reproduce or derive Pattrans Materials in order to build or train a competing product or service; this does not restrict your use of Customer Content, your My Termbase, or Output in which you retain rights under §7.1;
• (i) Malicious content — knowingly upload or transmit malware, malicious macros, exploit files, credential-harvesting material, or other code or content intended to compromise, harm or interfere with the Service, accounts, systems or other users;
• (j) Misrepresentation — knowingly provide materially false account, eligibility or payment information, or impersonate another person or organisation without authority;
• (k) Legal compliance — use the Service in violation of applicable law, including export, sanctions and data-protection law.

We may investigate suspected breaches and take proportionate action in accordance with §13, including suspending or terminating access and cancelling unused promotional Credits for fraud or abuse; immediate restriction or suspension may be used where reasonably necessary for security, legal or abuse-prevention reasons. We will not permanently terminate your account or forfeit paid Credits solely on the basis of an unverified automated fraud signal.

5. Purchases, Credits and payment

5.1 The Service is paid for with prepaid Credits. Purchased Credits are delivered electronically to your account after the seller confirms successful payment; delivery is normally automatic, but bank-transfer purchases may require payment reconciliation. If Credits are not delivered after your payment has been confirmed, contact us under §17 so that we can verify the transaction and deliver the purchased Credits. The number of Credits a translation consumes depends on the amount of text and the language pair, according to the rates we publish. The Credits required, and any applicable minimum charge, are shown before you confirm a purchase or a translation. We may change our rates as described in §5.5.

5.2 Credits are a prepaid usage credit, redeemable only within the Service to obtain usage of the translation functionality. Credits may be used only within the Service by the purchasing account. They cannot be transferred to another person, used to pay third parties or redeemed for cash, except where a monetary remedy is required by mandatory law.

5.3 Seller of record. (a) Some purchases (typically international checkout) are concluded with an authorised Merchant of Record / Reseller, which sells the applicable Credits or Plan to you in its own name; that party's purchase terms, refund handling, taxes and invoicing apply to the purchase. Pattrans separately grants and operates your access to the Software under these Terms. The Reseller's terms do not exclude any mandatory rights available to you under applicable consumer-protection law. (b) Other purchases (typically within Vietnam) are made directly from Pattrans as seller; our Refund Policy and Vietnamese invoicing apply. (c) The seller for your purchase (legal name and contact) is shown at checkout before you pay.

5.4 Applicable taxes are handled at checkout by the seller of the transaction.

5.5 Credit value and price changes. Purchased Credits keep their numerical balance and the word-processing capability they represent. The number of Credits required for a translation, and any minimum charge, are shown before you confirm it. We may change our prices; a price increase will not reduce the amount of translation you can perform with the Credits already in your account when the increase takes effect, and new purchases are charged at the new price. We will give at least 30 days' notice of an increase; decreases may take effect immediately.

6. Refunds

The Refund Policy is incorporated into these Terms and follows the two tracks in §5. Where a transaction-specific term shown at checkout conflicts with these Terms, the checkout term prevails only as to the price, quantity, Plan or Credits purchased, seller identity, taxes, payment, invoicing and transaction-specific refund terms for that purchase, and subject always to mandatory law. Nothing in these Terms limits your mandatory consumer-protection rights.

7. Your content and confidentiality

7.1 You retain all rights to Customer Content; you grant us only the rights needed to operate the Service and produce your Output.

7.2 You must not knowingly submit Customer Content that you are not lawfully entitled to submit. If you are a Business User, you represent that you have all necessary rights, lawful bases and authority for the processing of Customer Content — including any personal data of third parties contained in your documents — contemplated by these Terms and the Privacy Policy.

7.3 Confidentiality. We treat Customer Content as confidential and do not disclose it except to authorised personnel, to contracted providers bound by confidentiality obligations and acting for us, or where disclosure is required by law. We use Customer Content only to provide, secure, maintain and support the Service and, where you have opted in, to improve it. This does not apply to information that is or becomes public without our breach, was lawfully known to us, is lawfully received from a third party, or is independently developed without use of or reference to Customer Content. Where we are required by law to disclose Customer Content, we will, where legally permitted, give you prior notice.

7.4 Processing and AI. Customer Content may be processed by Pattrans's systems and, where applicable, by contracted infrastructure or AI providers. Depending on the systems or providers used, Customer Content and any personal data it contains may be processed in countries outside Vietnam, as described in the Privacy Policy. Pattrans does not use Customer Content to train general-purpose AI models and contractually requires applicable AI providers not to use it for such training. How we handle personal data — roles, legal bases, retention, cross-border transfer, sub-processors and your rights — is set out in the Privacy Policy, which forms part of these Terms.

8. Intellectual property

We, our affiliates and our licensors retain their respective rights in the Software, technology, models, components and website. These Terms grant you no rights in them except the licence in §2.

9. No warranty; your responsibility to review

9.1 The Service is provided "as is" and "as available". We do not warrant that the Output is accurate, complete, error-free, or suitable for filing or any particular purpose.

9.2 The Output is a machine-generated draft. You are responsible for reviewing and verifying it before filing, submitting, publishing or otherwise relying on it. The Service does not produce a certified, final or filing-ready document, and does not constitute legal or professional advice.

9.3 This §9 concerns the linguistic accuracy and suitability of the Output. It does not exclude our obligations relating to the operation of the Software, security, purchased functionality, or any express commitment we make.

10. Service availability

We aim to keep the Service available but do not guarantee uninterrupted operation; we may perform maintenance and modify features, provided that we do not materially remove paid core functionality during an active Plan, or materially impair your ability to use purchased Credits, without providing a reasonable alternative, a transition period, or an applicable refund. If Credits are deducted because of our system error and no usable Output is produced, we will restore the affected Credits to your account; this Credit restoration is not a cash refund.

11. Limitation of liability

11.1 To the maximum extent permitted by law, we are not liable for indirect, incidental, special or consequential loss, or loss of profit or goodwill. For Consumers, this §11.1 applies only to losses that were not a reasonably foreseeable consequence of our breach, and only to the extent permitted by applicable law.

11.2 To the maximum extent permitted by law, our total liability arising out of or relating to the Service is limited to the greater of: (a) the amount paid for the affected Credits or Plan (including amounts paid to a Reseller for those Credits or Plan); and (b) the amounts paid to Pattrans for the Service in the 12 months before the event giving rise to the claim.

11.3 §§11.1–11.2 do not apply to: fraud, wilful misconduct or gross negligence; breach of confidentiality; unlawful processing or disclosure of personal data; a claim that the Software or technology provided by Pattrans, used as permitted under these Terms, infringes a third party's intellectual-property rights (excluding claims arising from Customer Content, your instructions, or unauthorised modifications or combinations not supplied by Pattrans); death or personal injury; or any liability that cannot lawfully be excluded, including mandatory consumer-protection rights.

12. Indemnity (Business Users)

If you are a Business User, you will indemnify us against third-party claims arising from your infringement of rights, your unlawful content, or your breach of §4, to the extent caused by you. We will promptly notify you of the claim, allow you reasonable control of its defence and settlement, and provide reasonable cooperation; you may not settle a claim in a way that admits liability or imposes obligations on Pattrans without our consent. This §12 does not apply to Consumers.

13. Suspension and termination

13.1 We may suspend or terminate access for breach of these Terms or law, or to protect the Service, users or security. Except where immediate action is reasonably necessary for security, legal or abuse-prevention reasons, we will give notice and a reasonable opportunity to cure a remediable breach.

13.2 You may stop using the Service and close your account at any time. Before voluntary closure you should download your Output; any post-closure access, retention and deletion are governed by the Privacy Policy.

13.3 Credits on termination. If we terminate your account for an uncured material breach, we may cancel unused promotional Credits. Unused paid Credits will be handled in accordance with the Refund Policy and mandatory law; except where mandatory law requires otherwise, unused paid Credits are not redeemable for cash. If we close your account without your breach while the Service continues, we will restore access to your unused paid Credits through the same account or another account designated by you. If we permanently discontinue the Service, we will provide reasonable advance notice and a reasonable period for you to use unused paid Credits; any monetary refund required by mandatory law will be processed in accordance with the Refund Policy. If Pattrans becomes subject to insolvency or liquidation proceedings, claims are handled under applicable insolvency law. If you voluntarily close your account, unused Credits are handled under the Refund Policy. Consumer refund rights are unaffected.

13.4 Survival. Provisions that by nature should survive — including §§4, 5.2, 7, 8, 9, 11, 14–18, and accrued rights and payment obligations — survive termination.

14. Consumers

If you are a Consumer, mandatory consumer-protection rights under the law of your place of residence prevail over anything inconsistent in these Terms, and the limitations, indemnity and forum provisions apply only to the extent that law permits.

15. Changes to these Terms

We may update these Terms. Material changes take effect no earlier than 30 days after notice, except where an earlier change is reasonably required by law or to address an urgent security risk. Changes will not retroactively reduce rights attached to Credits already purchased. If a material change adversely affects your existing paid rights, you may reject it by closing your account before it takes effect and receive a refund for the materially affected unused paid Credits, subject to mandatory law; this does not apply to changes required by law where continued performance would otherwise be unlawful. Continued use after changes take effect means you accept them.

16. Governing law and disputes

16.1 These Terms and your use of the Software are governed by the laws of Vietnam. We aim to resolve complaints first through §17.

16.2 Subject to §16.3, any dispute is submitted to the competent authority having jurisdiction under the laws of Vietnam. A Reseller's purchase terms apply to claims arising from the sale it concludes, including payment processing, transaction taxes, invoices and refunds administered by that Reseller. These Terms apply to Pattrans's provision and operation of the Software, including account access, Customer Content, security, privacy and Pattrans's conduct. This allocation does not exclude responsibility that Pattrans or the Reseller has under mandatory law for its own acts or omissions.

16.3 If you are a Consumer, nothing in §16 deprives you of the protection of, or the right to bring proceedings under, mandatory rules of the law of your place of residence.

17. Complaints and contact

Contact: support@pattrans.ai. For complaints, email the same address; we aim to acknowledge within 5 business days and resolve within 15 business days. For Reseller purchases, billing and refund complaints may also be raised with the Reseller.

18. General

18.1 Order of precedence. These Terms, the Refund Policy, the Privacy Policy and any Data Processing Agreement together govern the Software-licence relationship and Pattrans's obligations; transaction-specific terms shown at checkout govern only the purchase-specific commercial matters listed in §6, and a Reseller's terms govern the sale it concludes. Checkout or Reseller terms do not amend Pattrans's confidentiality, data-protection, software-licence or liability obligations unless Pattrans expressly agrees in writing.

18.2 Entire agreement. These Terms and the documents incorporated under §18.1 constitute the entire agreement between you and Pattrans concerning the Software-licence relationship and replace prior communications concerning that relationship. Nothing in this clause excludes liability for fraud or misrepresentation or limits any right that cannot lawfully be excluded.

18.3 Assignment. We may assign these Terms as part of a merger, reorganisation, sale of business or transfer of the Service, provided that the successor assumes Pattrans's obligations and your rights are not reduced. Where applicable law requires your consent to a transfer, the transfer will not take effect in relation to you without that consent. You may not transfer your account or rights under these Terms without our consent, except where applicable law permits otherwise.

18.4 Severability; no waiver of a right by not enforcing it.

18.5 Notices. General notices may be posted on the Service. Notices materially affecting your account, paid rights, suspension or termination will be sent by email or in-app notice and are deemed received when delivered through that channel.

18.6 Force majeure. Neither party is liable for delay or failure due to events beyond reasonable control; this does not excuse refunding prepaid amounts for Service we can no longer provide.

18.7 Language. These Terms may be made available in English, Vietnamese and other languages. For Business Users, the English version governs unless otherwise agreed. For Consumers, the language version and interpretation required by mandatory law apply; where Vietnamese law applies and the Vietnamese and foreign-language versions differ, the version more favourable to the Consumer prevails.
