You specifically need a patent/IP lawyer. Someone else mentioned the EFF. You might also try the Software Freedom Law Center. They're specifically focused on open source but they might be able to point you in an appropriate direction.

Président of FFII.org here, we received several requests from small companies here in Europe. You can contact me at zoobab at gmail.com. We are now busy with the 3rd attempt to impose software patents in the EU via the UPC.
