Utilizing professional patent searchers, we can provide State-of-the-Art searches.
A basic State-of-the-Art search typically provides copies of in-force patents covering the basic subject matter of interest.
Depending on needs, the search can return a sampling of the patents in the basic subject matter area, or nearly all of those patents plus expired patents (a.k.a., a "collection" search).
Advanced searches can include searching websites, newsgroups, English-language non-patent literature, and/or foreign-language patents, applications, and literature.
