IP & Copyright

This page sets out the industrial property rights and the copyright behind the CashXChain platform: what is filed, what is registered, and what you may and may not do with our material. Each registered right links to the entry in the register of the granting office so that it can be checked independently.

At a glance

Each register link leads to the entry of the office that granted or is examining the right; all were retrieved on 8 October 2026. Further register and database entries, and the documents we publish ourselves, are given in the sections below.

1. Patent application

DE 10 2026 002 845.0 — filed with the German Patent and Trade Mark Office (DPMA)  (retrieved 8 October 2026) on 25 May 2026 and pending. It claims the domestic priority of utility model DE 20 2025 001 388.2 of 23 May 2025 under § 40 of the German Patent Act (PatG)  (retrieved 8 October 2026).

A German patent application is published, and only then appears in the public register, eighteen months after its priority date — for this application, in November 2026. Until then there is no register entry to link, and the DPMA’s acknowledgement of receipt is the record of the filing.

The application secures the priority date. In the meantime, the same subject matter is already protected in Germany by the utility model it claims priority from, which is registered and in force.

Record. DPMA acknowledgement of receipt of 28 May 2026 (PDF, first page; the postal address is redacted).

2. Registered utility models

Five utility models are registered at the German Patent and Trade Mark Office, in force and published.

Each entry gives the file number, the filing, registration and publication dates and the main IPC class, and links the register entry, the published document and a photograph of the registration certificate. The German title is the registered one and governs: an English title here is our translation of it, given for readability, and the German wording prevails where the two could be read differently.

Independently of registration, “CashXChain”, the CashXChain logo and our product names are used in trade and are protected as unregistered signs to the extent the law provides for that.

4. Copyright

All content, software, designs, documentation and other original works published or made available by CashXChain — including this Legal Center, the CashXChain platform, and all associated applications, APIs and interfaces — are © 2025–2026 CashXChain Inc. All rights reserved. CashXChain UG (haftungsbeschränkt) operates the platform under a licence from CashXChain Inc.

What that covers. Source code and object code; the structure, selection and arrangement of our APIs and their specifications and reference documentation; interface and interaction designs, layouts, icons and other graphic works; technical and product documentation; the text of every document in this Legal Center, including its German translations; and our marketing and website copy. It covers the works themselves, not the facts or legal positions they describe.

How the rights reach us. Works created by our employees and contractors are brought to CashXChain Inc. through their employment or engagement contracts. Under German law authorship stays with the individual who created the work and copyright itself cannot be assigned (§§ 7 and 29(1) of the Copyright Act (UrhG) , retrieved 26 August 2026); what is granted instead is an exclusive, unrestricted right of use under § 31 UrhG, including for types of use not yet known. Under United States law, works created by employees within the scope of their employment vest in the employer. The practical result is the same in both places: CashXChain Inc. controls the exploitation of the work.

Databases. Where our systems and this corpus constitute databases, the sui generis database right under §§ 87a to 87e UrhG, implementing Directive 96/9/EC, belongs to CashXChain Inc. as the maker of the database. That right is separate from copyright in the individual entries and applies even where the entries themselves are not protected.

Notices. Copyright arises on creation and without any formality under the Berne Convention: the absence of a notice on a particular page or file does not place that material in the public domain.

5. Third-party and open-source components

Our platform and this site incorporate third-party components, including open-source software. Nothing in this page claims any right in them.

Open-source components remain subject to their own licences. Nothing stated here restricts, and nothing here is intended to restrict, any right granted to you under such a licence. Where a licence requires attribution, the preservation of notices, or the availability of source code, we comply with it on the terms of that licence. Third-party trade marks, logos and product names named anywhere in this Legal Center belong to their respective owners and are used for identification only.

6. Using our content

You may read, print, download, quote and link to the documents in this Legal Center. Quotation should identify CashXChain as the source and must not alter the meaning of what is quoted; where you rely on a document, quote the version that is in force.

Beyond that, you may not copy, reproduce, distribute, publicly communicate, modify or otherwise reuse our content without our written permission, except to the extent the law allows without it — in Germany, for example, the statutory exceptions in the UrhG for quotation, press reporting, and temporary and incidental reproduction.

Text and data mining. This Legal Center is published to be read, indexed and quoted, by people and by automated systems alike, and our robots.txt and llms.txt say so. We do not restrict text and data mining of the documents in this Legal Center. For our software, our product interfaces and our non-legal content, we reserve the right of reproduction for text and data mining under § 44b(3) UrhG and Article 4(3) of Directive (EU) 2019/790; that reservation is made here in machine-readable form on a page a crawler reaches.

7. No licence

Nothing on our websites, in our documents or in this notice gives you any right in our marks, our patent or utility-model rights, our protected methods or our content, beyond using the service as intended. No right is granted by implication, by acquiescence or by estoppel. Where we do not enforce a right immediately, that is not a waiver of it.

8. Reporting infringement, and licensing

To report suspected infringement of our rights, to notify us that our material infringes yours, or to ask about a licence, write to [email protected]. A notice about content on our sites reaches us fastest if it identifies the material, the right relied on and the basis of the claim, and gives us a way to reply.
