Innovative from its beginning, Schwegman, Lundberg & Woessner was founded in 1993 proclaiming "NO LITIGATORS ALLOWED." Unlike conventional IP firms that tend to concentrate significantly more resources on litigation than on patent prosecution, SLW developed a new IP law firm model in which obtaining the strongest patents is the sole focus of the firm. Today, SLW has grown to over 80 attorneys with advanced degrees in the areas of electrical, computer/software, chemical and mechanical engineering, chemistry, molecular biology, and other life sciences. We represent a spectrum of multinational corporations, middle-market businesses, universities, startups, and individuals. For three consecutive years the firm was ranked number one in overall patent quality by Patent Ratings, LLC as reported in IP Law & Business magazine with top ten rankings in chemical, biotech, computers/electrical, and medical patents.
And the innovations continue. SLW has developed both the ClaimBot™ program to chart and index patent claims and the ClaimTracker™ software to manage prosecution history. Together these programs capture and organize information critical to prosecuting and managing patents and their claims, cross-referencing and storing the information allowing for instantaneous retrieval and cross-correlation of all prosecution data, including prior art. SLW is the only firm that captures and retains 100% of prosecution history information in this way. Now our attorneys and clients can use our databases to obtain a graphic overview of the history of claims, interactively surf file histories, study the citation history of prior art, or obtain additional reports – all available at the click of a button.
