"In some fields, there may be no getting around the practical difficulty of detecting patent infringement. For example, patents for computer-based inventions are often directed to the inner workings of computer hardware or software, which may not be readily apparent from the operation of an infringing device. Reverse-engineering competitors’ products may provide insight as to whether infringement is likely."
