Discover Important
Prior Art to Support Litigation


IP.com’s Patent Validity Search uncovers patents or other prior art, published before the earliest priority date of the target patent, which might render a granted patent invalid. We deliver a full validity/invalidity search report, a claims-mapping chart, and electronic copies of any cited prior art.
