Leash Locket receives patent approval

The American pet supplies company Leash Locket has received notice from the United States Patent and Trademark Office (USPTO) that all twenty-nine of its claims for its collar-mounted, retractable pet leash have been upheld as patentable. A utility patent allows the patent holder to exclude others from making, selling or using the invention for up to twenty years from the filing of the patent application. According to the company, Leash Locket’s design was perfected in over two years of development and production by a team of ten engineers and leading pet product experts.
