"Patents make our product defensible." The optimal number of times to use the P word in a presentation is one. Just once, say, "We have filed patents for what we are doing." Done.

"(Big name research firm) says our market will be $50 billion in 2010." Every entrepreneur has a few slides about how the market potential for his segment is tens of billions.
