The following passage was adapted from a law journal article 1998.
Industries that use biotechnology are convinced that intellectual property protection should be allowable for discoveries that stem from research and have commercial potential. Biotechnology researchers in academic institutions increasingly share this view because of their reliance on research funding that is in part conditional on the patentability of their results. However, questions biotechnology inventions are now the focus of increased scrutiny by scientists and policy makers.
The perceived threat to basic research relates to restrictions on access to research materials, such as genetic sequences, cell lines, and genetically altered animals. These restrictions are seen as arising either from enforcement of a patent right or through operation of a contractual agreement. Some researchers fear that patenting biological materials will prohibitively high fees for the right to conduct basic research involving the use of patented materials.
While it is true that the communal tradition of freely sharing research materials has shifted to a market model, it is also undoubtedly true that even in the early days of biotechnology, some researchers took measures to prevent competitors from gaining access to materials they had created. Scientists who resist the idea economic rewards as well as a degree of licensing control over the use of their discoveries.
What this question is testing
Your task
