Althearidge LLC

Althearidge LLC is a Texas-based limited liability company for which no public headquarters address, founding date, or employee information is available. The company maintains no public website and has no evident presence beyond its corporate registration and patent litigation filings. Its ownership is private, and there is no indication of it being a subsidiary of a larger corporation.

The company has no known products, services, or business operations. Public records indicate that Althearidge's sole activity is patent assertion. It is a non-practicing entity (NPE) that holds patents and seeks to generate revenue through licensing and litigation. In its April 2026 lawsuits, the company asserted two U.S. patents: No. 7,154,961 and No. 7,567,622. These patents generally relate to methods for modulating and transmitting data, including techniques for constellation rearrangement in digital communications.

Consistent with its status as an NPE, Althearidge LLC's litigation posture is that of a patent plaintiff. According to the provided case data, the company has filed two lawsuits and has never been named as a defendant. The cases were filed in the U.S. District Courts for the Eastern and Western Districts of Texas, which are historically prominent venues for patent litigation.

The company's litigation activity began on April 17, 2026, with the simultaneous filing of two lawsuits. The first suit, filed in the Eastern District of Texas, targets Cipherlab Co Ltd, a company that manufactures and sells automatic identification and data capture products like mobile computers and barcode scanners. The second suit was filed in the Western District of Texas against Viasat Inc., a global communications company that provides satellite internet and other connectivity solutions.
