Brand History & Trademark Analysis
Pyrex has been registered in the UK for heat-resistant glassware and kitchenware since the early twentieth century. The brand became a staple of British home cooking — virtually every British household owned at least one Pyrex dish. The trademark has been the subject of consumer controversy regarding the transition from borosilicate glass to tempered soda-lime glass in some markets, affecting product properties.

Historical Background
Pyrex was developed at Corning Glass Works in New York and the trademark was registered in 1915. The UK rights were licensed to James A Jobling & Co. of Sunderland, which began producing Pyrex in Britain in 1922. World Kitchen LLC acquired the Pyrex trademark in the late 1990s. In 2004, World Kitchen switched US Pyrex products from borosilicate to soda-lime glass, but Corning retained the EU licence and continued producing borosilicate Pyrex in Europe — creating the unusual situation where the same brand name covers products with different glass compositions on either side of the Atlantic.
