UH physicist gets patent for magnet after 20 years | Houston & Texas News | Chron.com - Houston Chronicle: "Roy Weinstein had given up.
To heck with the patent office, the 82-year-old physicist decided. After waiting two decades for a patent on his potentially revolutionary superconducting magnets, he'd had enough.
“As you might imagine, waiting 20 years is a pretty nasty chore,” said Weinstein, an emeritus professor at the University of Houston.
Then, amazingly, the patent arrived on Feb. 23 — 20 years and three days after he applied for it."
