Riach

Note on identity. The tracked entity "Riach" does not appear to be an operating company. Public court records identify the plaintiff in the single tracked case as George Riach, Jr., an individual inventor — not a corporation. I could not verify any company named Riach with headquarters, employees, revenue, or ownership status; no such entity appears in the sources reviewed. The profile below reflects what the record supports.

Company overview. No legal entity named "Riach" is verifiable as a business. The relevant party is George Riach, Jr., the named inventor on U.S. Patent Nos. 4,988,181 ("Ornamental device for eyeglasses," 1991) and 5,389,981 ("Eyeglasses having magnets attached thereto for improving the blood circulation of the eyes," 1995), plus a later application family (CA 2,216,280; WO 96/23241). Ownership status, headcount, and revenue are not applicable or verifiable.

Products / services. Riach's patents cover eyeglass frames and lenses fitted with permanent/ceramic magnets positioned so a north magnetic field projects onto the eye, asserted to improve blood circulation and reduce eye strain. There is no evidence of a manufacturing or retail operation; the patents were asserted by the inventor personally. This is best characterized as an individual inventor enforcing a small, self-held patent portfolio rather than a PAE with an acquired portfolio, though the posture (one plaintiff case, zero defendant cases) is typical of a non-practicing patent holder.

Patent-litigation posture. One tracked case, as plaintiff only: Riach v. Manhattan Design Studio, No. 00 C 5883 (N.D. Ill.). The venue is the Northern District of Illinois (Chicago), not an ED Texas-style plaintiff venue. The litigation concerned the '981 patent.

Notable cases / context. In a 25 September 2001 Markman/summary judgment ruling, the court construed the '981 claims to require the recited therapeutic effects as limitations, and granted the defendants' summary judgment of no infringement (literal and under equivalents), denying Riach's cross-motion; a 12 December 2001 ruling addressed the "exceptional case" fee standard. The Federal Circuit dismissed Riach's appeals on his own unopposed motion (35 F. App'x 880, Fed. Cir. 2002). Defendant Manhattan Design Studio, Inc. (formerly Ira Lerner, Inc.) was a magnetic clip-on eyewear maker also active in the parallel Aspex/Contour Optik litigation.
