Grant Goodrich to Abraham Lincoln, 24 May [1849]1
Hon A LincolnDr[Dear] Sir
My wife is so ill I shall not be able to go to Springfield to Court– I have advised Mr Chas Hoit to employ you in a case of Z Parker vs him. It is for violation of a patent for Reaction percussion water wheels–2 The testimony will be on hand Hoit will be there with his witnesses latter part of next week– I will send you in a few days a brief & the points as I suppose they will come up, By looking at narr[narratio] & notices you will see the main points– I presume you have the Patent Laws & decissions which were published I believe by Congress last winter–3
The first point which we shall make is 1st that reaction wheels were in use long before his patent, & 2 or more on a horizontal shaft, and that when there are different combinations of old machinery or principles to produce a given result, they must show we used all the combinations you will find a case in 16 Peters to this effect.4 It is an important case & Hoit is able & willing to pay a good fee– Our court is sitting, & as soon as I can get time I will write a full history of the case & give the points– Barber5 will be there & he will explain every thing clearly6
Yours in hasteGrant Goodrich

6Hoyt retained Goodrich, Abraham Lincoln, and George W. Meeker to argue his case. The suit came to trial on July 9, 1850, and concluded on July 24. The jury found for Parker, and Hoyt requested a new trial. The court granted Hoyt’s motion. In the second trial, the jury found for Hoyt, and Parker motioned for a new trial. The court granted his motion. The case lingered on through the early 1850s. In November 1854, Hoyt wrote Lincoln two letters asking for word on his suit. In July 1855, Lincoln succeeded in having the case dismissed in the U.S. Circuit Court, Northern Division of Illinois.
