Rotating EP w. Name v.1.1The Essential Patent LLC intellectual property law firm welcomes you to the Essential Patent Blog! This blog was started in response to increased interest and litigation surrounding standard-essential patents (SEPs). Historically, most SEP issues were relegated to theoretical discussions in academic literature or conference presentations. But that’s changing. Many in industry, the media, the legal world – and even Congress and administrative agencies – are paying increased attention to SEP issues. Several patent-related blogs previously had posts on SEP issues, but none focused primarily on the myriad legal issues and disputes surrounding SEPs. That’s where this blog come’s in with a goal of being the one-stop shop for all SEP litigation issues, hitting other “essential” patent law issues along the way.
