Practical Considerations of Patent Portfolio DevelopmentPractical Considerations of Patent Portfolio Development
•Disclosure – must fully disclose the invention to the public in return for monopoly (is trade secret protection more effective?)
•Cost – patents can be expensive to procure and maintain and are even expensive to enforce
•Time – inventors and others in company must invest time in process to obtain and enforce patents
•Process – patents generally require 2 - 4 years to obtain
•Possible Loss of Patent Rights – company must monitor sales efforts, publications, or other events that might result in loss of patent rights

Obviousness– Neither reference provides any suggestion or
motivation for making a thrombin variant that has two substitutions, let alone two substitutions W215A and E217A.
– Claimed invention is non-obvious because of the unexpected properties.
– The combination product WE has an synergy effect on reducing the release of fibrinopeptides A and B. See Tables 1 and 2» (Fibrinogen: E217A: W215A:WE =

*PA/FC here are calculated from the data shown in Tables 1 and 2. The term "PA/FC ratio" as used herein refers to the ratio of the percent of wild-type protein C activation (PA) activity remaining in a thrombin variant relative to the percent of wild-type fibrinogen clotting (FC) activity remaining in the thrombin variant. A value of PA/FC greater than 1.0 indicates that the thrombin variant has reduced procoagulant fibrinogen cleavage activity relative to the residual anticoagulant activity resulting from protein C activation.
