A prominent case appearing in the firm's record is Massively Broadband LLC v. Samsung Electronics Co., Ltd. et al., filed in the U.S. District Court for the Eastern District of Texas in June 2025, alleging patent infringement related to intelligent wireless broadband relay, smart antenna, and network monitoring patents. The litigation remains active, with docket entries showing motions for extension of time and initial discovery in late 2025. While specific outcomes for this case are not yet publicly detailed beyond initial filings, the firm's website highlights successful confidential settlements in significant intellectual property litigation.
