Hi everyone I am new to the forum and I would like to ask a question that is really bothering me because I cannot find answers anywhere on the web. The dealer was not even able to give me a answer?!? The problem, if it is a problem is the following: I just bought a Brand New Mesa Boogie Mark V head a couple of days ago exactly Sept 8th 2012, and when I checked the patents, to my surprise this is what I found?!? Mesa says that “No less than 9 patents stand guard over your tone…” well I would like to know why my new head has a 10th patent (7,602,927) along with all the other 9 patents. Is this a new improvement to the Mark V series? Why do I have a 10th patent? Thanks to all very very much… :roll: :roll:
Why does my Mark V head have a 10th patent?!?

This is strait from the U.S. Patent and Trademark Office under the Patent # which you listed in your post:
SUMMARY OF THE INVENTION
The amplifier of the present invention provides at least two user selectable output power levels in conjunction with a plurality of preamplifier channels and further provides switching such that the preferred output capability which best complements each channel's preamplifier setting can be assigned and automatically synchronized to the channels as they are selected during a performance.
In a typical embodiment of the present invention, the output amplifier would include four power vacuum tubes arranged in a push-pull parallel configuration. In its full power setting, all four vacuum tubes would be operable for maximum undistorted headroom. This is the power setting that would best complement a preamplifier channel set for a pure, clean style of playing.
A second preamplifier channel may be set with more gain and then be coupled to the power section alternately configured to operate this time on only a single pair of push-pull output tubes capable of delivering only about half the power of the previous setting. This enables the musician to generate desirable power amplifier distortion at a playing loudness that, while reduced from the maximum possible, actually better matches it in perceived loudness. This is because the amplifier stages, as they are driven increasingly hard into clip, progressively compress the dynamic peaks of the musical material. Thus, a less powerful output section that is driven harder can better match the loudness of a higher power section which is not overdriven and which is fed a more dynamic signal, such as is the case with clean picking or chording.
Amplifiers with more than two preamplifier channels (or modes) and/or more than two power output capabilities may, of course, utilize the channel-dedicated power amplifier switching of the present invention in a more expanded fashion as well as the amplifiers with only two preamplifier channels or two operational modes.
I don't know what any of this means.

Hey Knotts thank you so much for your help., but now i am even more confused?!? what the hell does all this mean (as you say)??? Take care and Rock on man. I hope Mesa gives me a straight understandable answer... :roll: :roll:

Guitar amplifier with channel-dedicated power switching
Abstract
An amplifier for electric guitar including a plurality of foot switch selectable preamplifier channels which can be set to provide differing sonic characteristics, and also including a power amplifier section for driving a loudspeaker that can be switched between at least two different power or performance capabilities. User operable switching dedicated to at least one of the preamplifier channels is provided to select preferred power amplifier parameters in conjunction with differing channel voicings. Thus, differing preferred power amplifier characteristics may be pre-set and assigned to individual preamplifier channels and called up automatically in conjunction with the remote channel selection.
Its just talking about having the ability of the different channels to be set at different wattage levels. So for the MKV it means you can have channel one set to 10watts, channel two set to 45watts and channel 3 in 90 watts, for example. And when you select the channels remotely (i.e. footswitch) the correct power section configuration is selected. The patent actually really is pretty straight forward. I've seen patents that left engineering and went through legal and when it came back to engineering the author no longer understood the patent. Engineers like to be specific, but the legal strategy is to make the patent as broad (and vague) as possible.
