CTNF 18/391,211 CTNF 77787 DETAILED ACTION Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. Election/Restrictions 08-25 AIA Applicant's election with traverse of the restriction requirement in the reply filed on 03/30/2026 is acknowledged. The traversal is on the ground(s) that there is not a serious search or examination burden . This is not found persuasive because the claims are clearly distinct and recite different features, utility, modes of operation, and/or method steps. Regarding invention I and invention II, applicant stated that the two inventions are the same, e.g. a transceiver system and method for operating the transceiver with local oscillator cross routing circuitry, however, this is not the only limitation in the recited claims. For example, invention I comprises selectively coupling a particular divider of the one or more dividers to the mixer, to at least one auxiliary mixer of the one or more auxiliary mixers, or any combination thereof, however invention II comprises receive a clock signal from a divider at a local oscillator cross routing circuitry, and selectively couple the divider to the primary mixer buffer, the auxiliary mixer buffer, or both, and processing, by the primary mixer buffer, the auxiliary mixer buffer, or both, the clock signal and providing the processed clock signal to a corresponding mixer, invention III has separate utility, components, and mode of operation using different circuitry such as selectively coupling at least one of the first oscillator or the second oscillator to the first mixer or to the second mixer via a corresponding auxiliary mixer buffer, and wherein the first oscillator and the first mixer are part of a first transmit or receive chain and the second oscillator and the second mixer are part of a second transmit or receive chain. Invention IV has separate utility, components, and mode of operation using different circuitry such as selectively couple the oscillator to mixers of multiple chains; and processing, by the primary mixer buffer, the first auxiliary mixer buffer, the second auxiliary mixer buffer of a second chain, or a combination thereof, the clock signal and providing the clock signal to a corresponding mixer of the mixers. These method steps, utilities, subject, and modes of operations using different circuitry/components are clearly different and distinct from one another, and thus it was determined by the examiner that the inventions are distinct inventions and require different fields of search such as using different search queries, different classification areas, and different search tools. These different searches would indeed cause a serious search and/or examination burden on the examiner if restriction is not required . The requirement is still deemed proper and is therefore made FINAL. Claim Objections 07-29-01 AIA Claim 8 is objected to because of the following informalities: claim 8, lines 5-6 recites “wherein the first second oscillator corresponds to a secondary…..”. The claim appears to be reciting ““wherein the second oscillator corresponds to a secondary…..” . Appropriate correction is required.
