Rory Parisien Has Invented a Mesh Screen to Keep Bugs

Rory Parisien has invented a mesh screen to keep bugs out of his cottage in the summer. Being a good steward of the environment, Rory had the unique idea of making the mesh biodegradable, so that when he replaces the mesh, he can just throw it away without harming the pristine environment around his cottage. There is, however, a problem with the mesh in that it biodegrades too easily. After a rainstorm or two, the mesh begins to disintegrate. Moreover, secretions from various bugs can have the same effect. Rory submits a patent for the biodegradable mesh screen designed to keep out bugs. Which of the following assessments is most accurate of his application?

A) It is patentable, despite its flaws.
B) It is patentable, so long as it is deemed non- obvious and novel.
C) It is not patentable because it will not be considered useful.
D) It is not patentable because it will not be considered novel.
E) It is not patentable because there would not be much of a market for the product.
