IPRs can be filed against small companies
From text within the Quad City post:
On Jan. 22, in Jacobs Corp. vs. Genesis III, Inc., the Patent Trial and Appeal Board, or PTAB, denied the IPR petition in all respects, finding that it "failed to demonstrate a reasonable likelihood that any of the challenged claims would be held invalid under any of several proposed theories."
“Contrary to what patent infringers may believe, the (United States Patent and Trademark Office) post-grant proceedings do not allow infringers to act with impunity against the exclusive rights enjoyed by a patent owner,” Jay Hamilton, founder and principal of Hamilton IP Law, said in a news release. "This decision denying the trial demonstrates that patent challenges at the USPTO can be defeated before expenses become crippling. The PTAB’s decision has strengthened the ‘569 Patent, recognizing the validity of all the patent claims in view of the three different proposed grounds of invalidity.”
