First of all, the present state of patent affairs (at least in the US)
makes me sick. There is nothing novel or unobvious to those in or out
of the field about using a combination of RGB LEDs to create shades of
color, as I am not a lighting expert and the idea occured to me many
times before I discovered that it is patented.

Yeah, it's a shit situation, but fortunately is only having a negative

I have also concluded that the color rendition by purely a combination
of red, green, and blue LEDs is rotten, and so I am planning to
construct lights for my own use based on a full spectrum of LED colors.
Ie, red, orange, yellow, green, aqua, blue, and violet.

Yeah, it's a shit situation, but fortunately is only having a negative
impact on America's lighting industry. Patent systems in other parts of
the world work properly.

It's already been explored. There are lights that use supplementary
colours for smoother pallets.

CK patent covers mixing of 2 colours or more.

Its having a not positive effect on medicine research as I understand
it, companies rushing to patent gene sequences that are pretty much as
prior art as you can get, but in a medicine may be a novel use which
is patentable.

Think US lighting industry sprouting Canadian offshoots to handle the
LED research. In meantime rest of us continue to enjoy rapid
development and falling prices.

p.s. looking for photie before Clive blackmails me with the one before
the hair transplant.

I don't think that will help. IIRC, legitimate research is exempt from
patent restrictions. On the other hand, if you want to sell into the US
market, you will need to address licensing issues.

It's worse than that. The whole picture shows you stroking a hot pussy.
