Mr. Sheerin ardently endorses and accepts payment in Bitcoin for any service rendered.

There have been several recent developments in U.S. patent law regarding the patentability of inventions implemented using the Internet.  I am well versed in the relevant case law and can provide valuable counsel as to whether your Bitcoin/Blockchain invention qualifies as patentable subject matter. In addition, I draft Bitcoin patents and Blockchain patents in a manner that helps ensure the subject matter is considered patentable, as well as draft claims that cover the invention broadly to help maximize the value of any issued Bitcoin patents and Blockchain patents.
