Challenging the Strong Presumption of Patent Validity

Patent Law Blog (Patently-​​O): Challenging the Strong Presumption of Patent Validity

One of the next major legal chal­lenges to patent rights will be against the strong pre­sump­tion of valid­ity asso­ci­ated with the patent grant. Section 282 of the patent act says only that a patent and its claims “shall be pre­sumed valid.” Under long­stand­ing doc­trine, this pre­sump­tion can only be over­come with clear and con­vinc­ing evi­dence of inva­lid­ity. The chal­lenge to this pre­sump­tion is most likely on two fronts: (1) expanded post-​​grant review and (2) court chal­lenges to the weight of the presumption.
