IPR PTABCast: Southwire v Cerro Wire
Summary: How to defeat rejection based on “inherency"
Patent claims can be invalid if a prior art reference teaches almost all the claimed features and any missing features must “necessarily” be present when you follow the Prior art teachings.
In this IPR PTABCast Craige explains how Southwire’s industry-changing process patent defeated the inherence attack but succumbed to the “obviousness” attack.
Check out this further case study on obviousness.

We were extremely pleased with the level of service we've received
We were extremely pleased with the level of service we've received from everyone at the Thompson Patent Law team. Costs were very fair & reasonable. And TPL worked to get us buttoned up with a very strong provisional utility patent—in very short time—and well in advance of a hard deadline we were up against. We will certainly be working with the Thompson Patent Law team down-the-road and on other patent-related issues as we continue to build our brand.
