Acadia Streaming Patent Contested
Anonymous Coward writes "Since last year Acadia Research has sent hundreds of letters to various porn web sites to arrange royalty deals, picking on the small fry before trying to take on well-heeled companies such as Disney. However, many small fries refused, and now 40 firms have joined forces and are embroiled in a suit with Acadia. Fish & Richardson (a prominent intellectual property law firm) have taken their case. The best part? CEO Paul Ryan's obvious sour-grapes-syndrome, he goes from describing the web porn industry as a "billion-dollar industry" where the money is to a "sideshow" that's "maybe 1% of our potential revenues".

You must be thinking of trademarks; see my comment on that. Patents cannot be lost by neglect to defend them. However, it may happen that the patent cannot be enforced in a certain case.
If company B has been infringing company A's patent for five years, and company A knew about it all along, and then suddenly decides to sue over it, B can use as a defense that, in effect, A's ignorage of the infringement excused it.
But if company C then comes along and infringes the same patent for the first time, A would still be able to enforce the patent on C. So patents are never lost completely, only partially under certain circumstances.
Also, this kind of situation doesn't tend to come up very often.
