I urge that guy to find a patent attorney. It can be very dangerous to represent yourself in such a case. It is usually dangerous to represent yourself, but for patent cases it is 10 times more dangerous, because:<p>(1) patent law is very complex. Even ordinary lawyers usually will not litigate patent cases unless they specialize in patent law only. Insurance companies will usually not insure attorneys that do not specialize in patent law for patent work.<p>(2) damages for patent cases can be very large. Damages can often break a company.<p>I read the post and he says some things that are simply wrong. For example the following statement:<p>"In order to be infringing on a patent, a person or entity must be infringing on every one of the claims that are linked together. Thus, an infringement would need to be on all of claims 1-10, or all of claims 11-20, or all of claims 21-23 for this patent."<p>is, in my humble opinion, wrong wrong worng!!! If you hang your hopes on the above you will have a nasty surprise waiting for you.<p>By the way, I am a patent attorney, but none of the above is legal advice. Just some friendly advice to get a lawyer.
