LQ PatentCast: Electric Power Group v Alstom

Published 2/19/18

Summary: Software is patentable – we do it here at TPL all the time. But many software inventions die a slow, and painful death in the patent office. Many others are killed off in litigation – all due to a Supreme Court case called Alice. Alice shapes which software claims thrive, and which don’t survive. In today’s EPG case, Craige explores how to identify whether claims will survive Alice. Craige also offers some Litigation Quality Patent practice pointers – including “red flag” phrases that are symptoms of potentially weak claims.

Case Study: How Not to Write Software Claims.

Software is patentable when you follow the rules.

This illustrates an avoidable, but all too common, flaw that leads to the demise of many software claims.
