U.S. Appellate Court Ruled Against CommScope and Reaffirmed Dali Wireless’ RAN Virtualization Seminal Patent

Dali Wireless, Inc. | August 31, 2021

Dali Wireless, Inc., a worldwide pioneer in digital radio distribution systems and digital predistortion technology received a decision on August 24, 2021, from the United States Court of Appeals for the Federal Circuit (CAFC). The CAFC affirmed most of the rulings made by Judge Barbara M.G. Lynn in the United States District Court for the Northern District of Texas in May 2020 (Case No. 3:16-cv-00477-M), including CommScope’s infringement of and the validity of U.S. Patent No. 9,531,473 (‘473).

Albert Lee, CEO of Dali Wireless stated, “We are thrilled to see that our ‘473 virtualized RAN patent has been affirmed. Dali is a pioneer in next generation wireless technologies, and our patent portfolio builds the foundation of virtualized wireless networks, especially in 5G. With this decision, we can now focus on innovating more disruptive technologies for the future.”

In May 2019 Dali Wireless filed a second patent infringement lawsuit against CommScope in the U.S. District Court for the District of Delaware, alleging infringement of U.S. Patent Number 8,682,338 (Case No. 1:19-cv-00952-MN). In this case, Dali is seeking damages and an injunction to stop the manufacture, sale, and distribution of CommScope’s OneCell® in-building system. This lawsuit is set for trial in March 2022.

Dali’s dedication to innovation has resulted in the company being granted over 500 global patents and pending patent applications. In addition to providing broad coverage on digital predistortion and radio frequency (“RF”) distribution technology, Dali’s patents are critically important to enabling 4G, 5G and virtual Radio Access Network (vRAN) technologies.

A FinOps-centric Approach Helps Enterprises Track and Control Cloud Costs as Per ISG

ISG | December 30, 2022

The growing use of public clouds by enterprises is leading to an increase in cloud costs, prompting a rise in demand for FinOps platforms to monitor and control expenses, according to a report by technology research and advisory firm Information Services Group. This rise in demand for FinOps platforms reflects a change in the enterprise cloud space, where companies are now looking for solutions that give them more accurate cost insights and better control over how much they spend on the cloud. FinOps platforms, which help clients manage their global IT assets and cut costs, are becoming an important part of the public cloud ecosystem as companies adopt multi-cloud strategies and take stock of how they use the cloud and how much it costs them. FinOps platforms are becoming more popular, which gives businesses a better view of their cloud costs and more control over how much they spend on the cloud. "According to predictions, the finops market will expand by more than 30% in 2022, and future growth will probably be faster." The report named Apptio (Cloudability), Flexera, HCLTech (MyXalytics), NetApp (Spot), and VMware (CloudHealth) as leaders in the Cloud FinOps Platforms quadrant. These platforms provide customers with a comprehensive view of their cloud consumption and costs, allowing them to gain better control over their spending and make decisions that drive operational efficiency and reduce costs.
