Of KSR:

“The combination of familiar elements according to known methods
is likely to be obvious when it does no more than yield predictable results.”
KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 416 (2007).
If a person of ordinary skill can implement a predictable
variation, § 103 likely bars its patentability. For the same
reason, if a technique has been used to improve one device, and
a person of ordinary skill in the art would recognize that it
would improve similar devices in the same way, using the
technique is obvious unless its actual application is beyond his
or her skill. Id. at 417.

Of the value of a reference:

In addition, a reference disclosure
is not limited only to its preferred embodiments, but is available for all that it
discloses and suggests to one of ordinary skill in the art. In re Lamberti, 545
F.2d 747, 750 (CCPA 1976).

“The fact that the motivating benefit comes at the expense of another
benefit … should not nullify its use as a basis to modify the disclosure of
one reference with the teachings of another. Instead, the benefits, both lost
and gained, should be weighed against one another.” Medichem S.A. v.
Rolabo S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006).
