American
manufacturers with adequate
resources could economically have their engineers and legal
representatives examine proposed tool designs with a view towards
picking long-used designs known for their ruggedness and ease of
manufacture while avoiding infringement of active patents. This also
was necessary in order to obtain protection of an innovative design or
substantial improvement. On the other hand, German manufacturers had a language barrier that increased the cost of navigating the United States' extensive patent literature and laws, so they generally chose an alternative plan: Follow the teachings of an expired U.S. patent, which the U.S. patent laws essentially required American inventors to make possible in order for the patent to be awarded in the first place. |
