*Source: List of top 300 organizations receiving US patents in 2013 published by the Intellectual Property Owners Association®. Patents received by each of those organizations were independently researched by Patent Buddy, LLC. Reasonable efforts were made to validate and match the patent counts found by Patent Buddy, LLC, to those indicated in the IPO® report. There is no affiliation between Patent Buddy, LLC, and the IPO®.
Patents issued by each firm were determined from the attorney representation indicated on the face of the patents issued to organizations in the top 300. Because some patents are issued without indication of the attorney representation on the face of the patent, or the name of the law firm may have changed, the actual number of patents issued by each firm may differ from the count obtained by Patent Buddy, LLC. As a result, while Patent Buddy, LLC has made reasonable efforts to identify firms in its TopFirms feature, it cannot guarantee the accuracy of the results.

**Note: Please note that the PBTop100 and PatentBuddyTopFirms patent counts are based on patents issued for Top 300 organizations only. Most if not all law firms issue patents for many more organizations such that the total number of patents issued by such law firms is larger than the count for Top 300 organizations only.
