Prior art

The search for US patent RE50328 on the USPTO database and Google Patents did not yield a patent document. Instead, the results consistently pointed to "RE50328" as a part number or product identifier, specifically for a "Selective Control Valve Controller" from John Deere.

Given the instruction to "Interpret patent numbers and identifiers literally; do not auto-correct them" and to "prioritize the search results as the current ground truth" if they contradict training data, it is concluded that RE50328 is not a valid US patent number in the format requested for patent analysis. US reissue patents typically follow the format "RE XXXXX", where XXXXX are digits. The literal interpretation of "RE50328" as a patent number did not lead to an actual patent document.

Therefore, without a valid US patent RE50328, it is not possible to identify its claims, specification, or relevant prior art under 35 U.S.C. § 102.
