IP & Copyright

This page sets out the industrial property rights and the copyright behind the CashXChain platform: what is filed, what is registered, who holds it, 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

1. Patent application

DE 10 2026 002 845.0 — filed with the German Patent and Trade Mark Office (DPMA)  (retrieved 26 August 2026) and pending. It claims priority from utility model DE 20 2025 001 388.2 under the Paris Convention for the Protection of Industrial Property.

A German patent application is published, and only then appears in the public register, eighteen months after its priority date. Until that point there is no register entry to link, and the application is deliberately not described here in more detail than the file number.

A pending application confers no enforceable exclusive right. What it does is fix the priority date, and the two registered utility models below already protect the same subject matter in Germany in the meantime.

2. Registered utility models

Two utility models are registered at the DPMA and in force. Both are currently held personally by our founder, Valentin Israel. Assignment to CashXChain Inc. is planned as part of the ongoing corporate restructuring, and this page will be updated when it is recorded in the register.

• Payment system with blockchain integration (Zahlungssystem mit Blockchain-Integration) — DE 20 2025 001 388.2. Filed 23 May 2025, registered 26 June 2025, publication of the registration in the Patentblatt 7 August 2025. Main IPC class G06Q 20/08. Published document DE 20 2025 001 388 U1. Register entry  (retrieved 26 August 2026).
• Routing engine for digital payment networks (Routing-Engine für digitale Zahlungsnetzwerke) — DE 20 2025 003 738.2. Filed 2 December 2025, registered 19 January 2026. Register entry  (retrieved 26 August 2026).

A German utility model is registered without substantive examination of novelty and inventive step. It confers an exclusive right that can be enforced, but validity is examined only if it is challenged in cancellation or infringement proceedings. We state that distinction rather than let a registration number imply more than it carries.

3. Utility models pending registration

Three further utility models were filed with the DPMA on 2 December 2025 and are awaiting registration. The DPMA creates a public register entry on registration, so there is nothing to link for these yet.

• Device for the technical enforcement of regulatory and safety-relevant requirements in digital payment transactions — DE 20 2025 003 741.2.
• Device for forecast-based capital allocation and technical pre-initialization of payment infrastructures — DE 20 2025 003 743.9.
• System for the unified abstraction of multiple payment infrastructures into one digital wallet — DE 20 2025 003 744.7.

Patents and utility models at the DPMA can be searched in DPMAregister  (retrieved 26 August 2026).

4. Trade marks

CashXChain is filed as an EU trade mark with the European Union Intellectual Property Office (EUIPO) under application number 019403993, held by CashXChain Inc. It covers classes 9 (software), 36 (payment and financial services) and 42 (platform and API services) across all 27 EU Member States. The application was made under the EUIPO Fast Track procedure; publication was on 16 August 2026 and registration is expected on 16 November 2026, subject to the opposition period passing without opposition.

The status is application pending. Once registered, the mark will be searchable in the EUIPO eSearch register  (retrieved 26 August 2026).

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.

5. 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 made for hire vest in the company directly. 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. The copyright notice on our pages and in our PDFs is generated from a single source so that it cannot drift between them. 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.

6. 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.

7. 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.

8. 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.

9. 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.
