What Portfolio Age Tells You

Fresh portfolios (high 2020+ %):

Domains with most IP filed in 2020+ are in a hyper-active filing phase. Prior art is still thin, claim scope tends to be broader, and the competitive landscape is still forming. High patenting velocity = high legal uncertainty.

Legacy-heavy portfolios (high pre-2000 %):

Mature domains with old patents will see large portions expiring in the next 10–20 years. This represents significant public-domain opportunity — products built on expired IP face no licensing cost from those patents.

Mixed-era portfolios (2000–2019 dominant):

The bulk of 20-year patent terms running 2000–2019 expire 2020–2039. These are the "middle generation" patents — old enough to have survived continuation pressure, new enough to still be in force.
