You need ammunition for an opposition or infringement case?


For over 15 years Patentcheck provide IP lawyers and patent attorneys with validity searches ranging from 10 to 200+ hours. The depth of analysis required for validity cases is our speciality and at times clients 'go by Patentcheck's compass'.


Cases, which can be in any technical field bar chemistry, are treated with utmost confidentiality. However we are not regulated by any body apart from ourselves and our reputation. Please feel free to ask references from client patent attorneys.


As instruction a patent number as email subject heading suffices, but further details by email or phone are welcome too. Challenge us, we strive tenaciously to find 'silver bullets' and often succeed!
