explanation why the term "dynamic" or dynamically should be interpreted under the second
listed definition as opposed to the first definition. Note, that Dr. Kurfess, van Engelen's expert,
provides no explanation as to why the proposed second definition is what one of ordinary skill in
the art would understand the definition to be (Ex. 2012 T 39). Generally, it is the first listed
definition that is the most commonly used definition for a given word. A dynamic market would
appear to have nothing to do with two mechanical frames and the relationship between those two
frames. Furthermore, van Engelen's proposed definition would require a structural element
between the two frames. Lee's claim 2, however, does not recite an element for isolating the two
frames. Rather, the claim merely recites the relationship between the two frames. The
relationship is described by the term dynamically isolated. We will not read limitations into
Lee's claims that would require an element to be in between the two frames. Lee's claim 2 is not
so limiting. Van Engelen's proposed definition is ultimately obtained by looking to its own
specification and importing limitations from its specification into the count. However, the count
is Lee claim 2 or van Engelen claim 2. Each alternative of the count is interpreted in light of the
parties' respective involved specifications. The first alternative of the count (Lee claim 2) is
interpreted in light of Lee's involved '763 specification.
With that in mind, a more reasonable interpretation of the term "dynamically isolated"
may be gleaned from the first definition for the word "dynamic" and from Lee's specification.
The first definition for dynamic is "of or relating to energy or to objects in motion" (Ex. 2017).
That definition, on its face, is a more reasonable definition for the term dynamic when considered
in the context of two frames and their relationship. Lee's '763 specification describes two
frames that are isolated from each other, such that the reaction forces from the elements of one
