Utilizing professional patent searchers, we can provide non-infringement searches.
Upon suspicion or notification that a patent owner might or has alleged that a product or service infringes the owner's patent, most well-counseled entities obtain a non-infringement search and opinion to determine if the infringement claim has merit, and/or to insulate against an allegation of willful infringement.
A basic non-infringement search typically includes searching the most related technology areas for in-force (and sometimes expired) US patents with claims of interest.
Advanced non-infringement searches can include searching for US patents classified beyond the technology area of the product of interest, for patents having "blocking" claims, and/or obtaining the prosecution history of any relevant patents.
