Walgreen Co.

Cascades Branding Innovation LLC initiated a patent infringement lawsuit against Walgreen Co., asserting that the retailer's mobile applications and online services utilized technology protected by U.S. Patent No. 8,131,597. This case was part of a series of lawsuits filed by Cascades against various companies, alleging infringement of their patent portfolio related to brand-based information access.

The central issue in the lawsuit was whether the patent's claims were valid and if Walgreens' technology infringed upon them. Similar to the later case against Aldi, Inc., the validity of the patent was a key point of contention. The court ultimately dismissed the case, finding that the patent was directed to an abstract idea and was therefore not eligible for patent protection. This ruling was a significant setback for Cascades and its efforts to enforce this patent against other companies.
