Patent cases are very discovery intensive, and many courts now have “patent local rules” that provide regulated process by which plaintiffs disclose their infringement contentions (i.e., explanations of why the defendant’s acts infringe the plaintiff’s patent) and by which defendants disclose their invalidity contentions (i.e., explanations of why the plaintiff’s patent claims are invalid). These […]
Read more →Lately we have been working some inventors who are newer to the patent process, and they are often concerned about providing details about the embodiments of their inventions. Their concern is that when we ask for this information, it means we are narrowing the scope of their invention. However, that is not the case. We […]

However, that was not all that changed with the implementation of the AIA. The AIA includes some significant changes to the on-sale bar which […]

Describing a device based on how it works is often referred to as “functional claiming.” Claims that make use of functional claiming are frequently broader in scope than those […]

CLS Bank, 134 S.Ct. 2347 (2014), the Patent Office has been aggressively rejecting software patent applications and the courts have been invalidating issued software patents for lack of […]

International Trade Commission, a case which demonstrated how limiting descriptions of an invention in a patent specification can be used to restrict the scope of otherwise facially broad claims. This month, in ScriptPro, LLC v. Innovation Associates, Inc.,the Federal Circuit […]

As we explained, both the Written Description and Enablement requirements of U.S. patent law may limit claim scope even if the prior art does not. […]

Myriad Genetics, Inc., et al., the U.S. Supreme Court held on June 13, 2013 that naturally-occurring, isolated genes are not patentable because they do not constitute patentable subject matter under the Patent Statute. With this decision, another chapter has been written in the […]
Read more →Well, we thought so, but now we are not so sure. It seems that the much more is required than the business method itself in order to obtain a patent. The cases suggest that, at a minimum, novel computing features are required. The Federal Circuit’s most recent pronouncement on the issue seems to change little […]
