Suppose the Claim 1 of a patent is as follows:
An assembly comprising:
a threaded nut positioned at least partially within the housing such that the nut is fixed against rotation with respect to the housing, wherein the threaded nut is ...;
If an assembly incorporates an "unthreaded nut" rather than a "threaded nut", would that avoid infringing the patent completely irrespective of the rest of the conjunctive clauses/claims? That is, could a specific minor change avoid infringing a claim?
Similarly, could a "threaded nut" be used as long as it isn't fixed against rotation?
Any thought appreciated.
