Drug Exclusivity. Exclusivity is the sole marketing rights granted by the FDA to a manufacturer upon the approval of a drug and may run simultaneously with a patent. Exclusivity periods can run from 180 days to seven years depending upon the circumstance of the exclusivity grant.
Nationally, the cost to install a fence averages around $2,600, with most homeowners spending between $1,580 and $3,669. This data is based on actual project costs as reported by HomeAdvisor members.
The Government Accountability Office in 2009 said the cost to build a mile of the fence initially averaged between $2.8 million and $3.9 million. But that was in the easiest areas, near metropolitan centers; other areas in the desert or mountains could cost as much as $16 million a mile.
