Editing Magnetic-core memory (section)

===Patent disputes===
Wang's patent was not granted until 1955, and by that time magnetic-core memory was already in use. This started a long series of lawsuits, which eventually ended when [[IBM]] bought the patent outright from Wang for {{USD|500,000}}.<ref>{{cite web|url=http://www.computerhistory.org/tdih/March/4/ |title=An Wang Sells Core Memory Patent to IBM |access-date=12 April 2010 |publisher=Computer History Museum |location=US}}</ref> Wang used the funds to greatly expand [[Wang Laboratories]], which he had co-founded with Dr. Ge-Yao Chu, a schoolmate from China.

MIT wanted to charge IBM $0.02 per bit royalty on core memory.  In 1964, after years of legal wrangling, IBM paid MIT $13 million for rights to Forrester's patent—the largest patent settlement to that date.<ref>{{cite web |url=http://www.computerhistory.org/revolution/memory-storage/8/253 |title=Magnetic Core Memory |work=CHM Revolution |publisher=Computer History Museum |access-date=1 April 2018}}</ref><ref>{{harvnb|Pugh|Johnson|Palmer|1991|p=[https://archive.org/details/ibms360early370s0000pugh/page/182 182] }}</ref>
