The search for prior art is a key component of the patent prosecution process, but it can often be time-consuming and costly. The US Patent Office issued 382,139 patents in 2004 alone, and as more and more patents are being filed, the need for accurate and effective prior art searching becomes even more essential. Patent offices in most major IP jurisdictions will perform patent searches. However companies are still choosing to scour patent office records, trade journals and patent databases themselves, to verify that no identical, similar or partially similar patents already exist. Although there is no affirmative duty to conduct a prior art search before filing a patent application, inventors and their attorneys are required to submit any prior art that they are aware of. A comprehensive search can therefore help support not only a patent application, but also licence negotiations, re-examinations and litigation further down the line. After all, an issued patent will stand up better in court with prior art to substantiate it.
