Reasons for invalidating a patent olderwomandating com review

For example, in certain scenarios, as per US laws, a U. patent application publication of a National Stage application and a WIPO (World Intellectual Property Organization) publication of an international application are considered to be prior art as of the international filing date only if the international application was filed on or after November 29, 2000 designating the United States and was published in English.

Once the priority date is established for the patent to be invalidated, the searchers next goal is to find references (non-patent literature or patent literature) which are available before the established priority date and disclose the claimed limitations of the patent in question.

A searcher has to analyze the claims of the patent to be invalidated to determine the first patent application in the entire family, which discloses all the limitations in the claims (at least the independent claim) of the patent to be invalidated.

In most of the cases, majority of the features may be disclosed in the previously filed patent applications, however there may be features which are be disclosed only in the patent to be invalidated.

In case a searcher faces any difficulty in identifying the priority date, it may be better to discuss the same with the attorney and the client.In such scenarios, searchers can utilize web archive resources like “waybackmachine.org” to check whether the disclosure is available before the established priority date.Searcher should also keep in mind that every search is different and a single protocol for all searches does not exist.NPL includes any public document or disclosure other than patent literature.One common problem faced with NPL’s is in determining the date they are made available to public, for example, disclosure on websites may sometime not include date on which it is made available.
