method claims

It Isn’t Kosher

As the reader may (should) remember, basically there are two kinds of patent claims: article claims¹ and method or process claims. Article claims are comprised of multiple article limitations, and method claims are comprised of multiple steps or process limitations. Both types of limitations are fine but, just as we are abjured to mix milk and meat, so too we are directed – albeit by a different authority – not to mix article limitations and process steps in a single patent claim.
