Can a company respond to two topics with the same principal investigator (PI)? Will that justify the one-half time PI commitment?

The principal investigator must have primary employment with the small business. Primary employment means that more than one-half of the principal investigator/project manager’s employment time is spent in the employ of the small business. This precludes full-time employment with another organization. The percentage of effort the PI is required to dedicate to one particular SBIR award is not stipulated.
