"Two Probe (Pre-Matched) Tuner": Patent Re-Issue

US Patent 6,674,293 (Adaptable pre-matched tuner system and method), which, due to weak claim language, has been object of a litigation regarding infringement, has been re-issued (application 14,013,156) with corrected and updated claim language (Patent no: RE45667).
The updated version is more robust and covers now the totality of multi-probe slide screw impedance tuners using metallic probes (slugs).
