Company patents

Pratt Retail Specialties, LLC

Pratt Retail Specialties, LLC's patent strategy is overwhelmingly concentrated in Containers & Packaging, representing 100.0% of its portfolio, yet this core area has seen a significant decline in patenting activity, with a -58.8% drop so far in 2026 compared to 2025. While the company has some diversification into Refrigerators & Cold Storage (34.9% of portfolio) and Packaging Machines (11.1%), these areas also show recent declines, suggesting a broader shift in patenting priorities away from new filings across its historical focus areas.
