1. Melt extrusion can be patented in several ways, including patents on the combination of an active substance and excipients used in melt extrusion or patents on the specific process of manufacturing a product through melt extrusion. 2. The best patent protection is to claim the active ingredient regardless of form and to claim various specific forms that include an inventive step beyond the prior art. It is also beneficial to claim a broad range for the combination of active ingredient and excipients. 3. To achieve the strongest validity, claims should focus on the specific process and specific combination, as these are most likely to prevent competition that uses a different process or excipient.
