Welcome to the G.E.I. KRAMER & HOFMANN mbH

Our company has specialized in databases and information systems for customers from industry, law firms and institutes since 1989. Our focus is on patent information systems with our main product XPAT, which supports all facets of patent work with various modules:

To round off our system around the topic of "Intellectual Property", we offer further important modules in addition to the patent information system XPAT, the intellectual property rights management XPAT AKTE, the trademark and design information systems XPAT Trademark and XPAT Design.

Knowledge management in the company is incredibly important. Who is not vigilant here, wastes great potential. This is where our product XPAT KnowIng comes in, documenting knowledge, making it available to target groups and keeping it up-to-date with the help of the software.

Patent departments are constantly researching the state of the art, for freedom-to-operate and also whether company-internal invention disclosures can be sustained. To avoid always having to start from scratch, we have implemented the XPAT RecDoc module, which documents these searches. The searches are thus reproducible and it is possible to continue searches that have already been carried out. Thus, one no longer starts from scratch, but builds on what has already been achieved. In addition, there is a feature for researching the legal validity of a document.

Another important field is covered by XPAT IP Meeting. After patent circulation, it is necessary for experts to exchange ideas on how to proceed with IP rights? Should IP rights be dropped, should an opposition be filed, should invention disclosures be claimed? All of this will be documented and meetings will be easily organized in the future.

As a supplement to these standard modules, we also offer patent databases, knowledge management systems, database-supported portal solutions, the standards information system XPAT Standards and much more, all individually created for our customers on the basis of the software Interhost developed by us.
