ST. PAUL, Minnesota, August 11, 2026
Egg Medical, Inc., a medical technology company focused on radiation protection for healthcare professionals, announced that Rampart IC, LLC has withdrawn its appeal of a U.S. Patent and Trademark Office (USPTO) reexamination decision involving U.S. Patent No. 11,660,056. According to Egg Medical, the USPTO’s reexamination determined that the claims of the Rampart patent as originally granted were invalid. Egg Medical said the decision followed its request for reexamination after Rampart previously brought a patent infringement lawsuit against the company. The development represents an important intellectual property milestone for Egg Medical as it continues advancing technologies designed to reduce occupational radiation exposure during image-guided medical procedures.
USPTO Reexamination Changes Patent Landscape
The patent dispute centers on Rampart’s U.S. Patent No. 11,660,056 and the scope of its originally issued claims. Egg Medical said the USPTO’s reexamination concluded that the inventions covered by the original claims were either previously invented by others, including Egg Medical, or represented obvious variations of existing work. Rampart subsequently withdrew its appeal of the USPTO reexamination decision, leaving the original invalidation decision in place according to Egg Medical. The company further stated that claims that may remain after the reexamination resulted from Rampart making material limitations to the originally issued claims, thereby narrowing the scope of the patent. Egg Medical said the reexamination was initiated after Rampart sued the company for alleged infringement of the original patent. Following the USPTO decision and Rampart’s withdrawal of the appeal, Egg Medical has notified Rampart of its own earlier patent and demanded that Rampart cease what Egg Medical characterizes as infringing activities. The companies’ intellectual property positions remain an important aspect of the ongoing technology landscape surrounding radiation protection systems for interventional healthcare environments.
Egg Medical Focuses on Radiation Protection Technology
The patent development comes as Egg Medical continues to focus on technologies designed to protect healthcare professionals who work with X-ray imaging systems during diagnostic and therapeutic procedures. The company develops an Enhanced Radiation Protection Device (ERPD) designed to reduce scatter radiation exposure for medical teams without requiring permanent room construction or creating additional workflow obstacles. Egg Medical describes its technology as a whole-room radiation protection approach intended to protect the entire procedural team during image-guided interventions. Occupational radiation exposure is an important consideration for physicians, nurses, technicians, and other healthcare professionals who routinely work around fluoroscopy and other X-ray-based imaging systems. Unlike patient exposure, which is generally associated with individual procedures, healthcare workers can experience repeated occupational exposure over their careers. Technologies that can reduce scattered radiation while maintaining access to the patient and imaging equipment therefore represent an important area of MedTech innovation and radiation safety.

Intellectual Property Supports MedTech Innovation
Egg Medical said the conclusion of the Rampart appeal reinforces the importance of protecting inventorship and intellectual property within the medical technology sector. The company emphasized that it intends to continue investing in its radiation protection technology and maintaining its focus on solutions that address the needs of healthcare professionals. Its ERPD technology is designed around scatter radiation reduction, while avoiding construction requirements, rolling trip hazards, and interruptions to clinical workflows. The withdrawal of Rampart’s appeal marks a notable development in the patent landscape surrounding radiation protection technologies. While the USPTO proceedings concern specific patent claims and do not by themselves establish the broader commercial or clinical performance of competing technologies, the development provides Egg Medical with an important intellectual property milestone. Egg Medical is continuing to focus on advancing radiation protection solutions that can help reduce occupational exposure while supporting efficient workflows in image-guided procedures. As medical imaging continues to play a central role in minimally invasive diagnostics and interventions, radiation safety technology remains an important area of healthcare innovation. Egg Medical’s continued investment in its ERPD platform reflects efforts to address occupational radiation exposure without compromising procedural access or workflow. The company said it will remain focused on developing technologies that support healthcare professionals and the hospitals in which they deliver image-guided care.
