Chip Firm Hit By 45-Year-Old Patent

JPMH writes "The Register is reporting that a Taiwanese chip foundry is being sued over two chemistry patents, one over 45 years old. The patents at issue were filed in 1957 and 1964, but are still in force because they were not granted until 1987 and 1992 respectively. The first patent, 4,702,808, details an apparatus and method for initiating chemical reactions by focusing "radiant energy, such as a laser" onto streams of particles. The second patent, 5,131,941 also details an apparatus and method for initiating chemical reactions, but this time radiation is used to provide the energy kick needed to get the compounds to interact."
