Apple have thousands of patents awarded each year (the system in the US is different to Europe where it is harder to get a unique patent) but that still didnt stop the stock market marking Apple down recently. Sony also have thousands of patents every year likely as many as Canon.
Apple had less than 2,000 US patents issued in 2013, around 1,200 in 2012, and just over 800 in 2011. Apple has ~7700 patents total. Canon has averaged over 2,000 patents per year for the past 15 years (meaning they've had more patents granted in the past 4 years than Apple has had since the Steves founded the company). Canon has been in the top 5 worldwide for issued US patents each year for >20 years. In other words, they have a long history of innovation.
Apple is trading recently much closer to its 52-week high than to its 52-week low.
Regardless, the point is that you seem to be implying that Canon is not innovating, and that's simply not the case.
It seems like they are innovating in AF and some other stuff but what everyone means is they want Canon with a better sensor then Sony's. I am sure Canon has something its just how long does it take to make and are they still working on it? even the high MP canon is still not out to compete with Nikon so i am sure they have something and waiting for the right time to release it. I am perfectly happy with my 5d iii but if i had the chance to get something better then Sonys sensor or even close to the same i would want it but that's eventually going to be on Canons system.
Could Canon just be milking out the profits on the current sensor tech? and just waiting until the last moment to release there new sensors?
for clarity, I will ignore Rebels, EOS-M, and SL-1 and concentrate on the higher end cameras.
So the last DSLR to come out (the 70D) comes with DPAF... a new sensor using new technology.... so to speak, a game changer for sensors..... It has done nothing to stop the forum members from crying about milking old sensor technology... The 1DX, the 5D3, the 6D, and the 7D have not been updated since the release of the 70D, but is there a single person here on the forum who does not think that DPAF is going to find it's way into these models in the next update cycle?
New technology is not retroactive. You can't go back in time and have it appear on past products... it rolls out in future releases.
WiFi came out on the 6D. Every camera after it (70D) has WiFi and you can bet that the 7D2, 5D4, and 1DX2 will have it built in.
Touchscreens came out on the 70D and you can bet that the 6D2, 7D2, 5D4, and 1DX2 will have it.
Watch what happens on the 7D2.... there is real potential that the 63 focus points we now think is so wonderful will become 10 million focus points and we will be able to track focus on a face in the crowd or a bird flying through the trees..... That is innovation. Adding a few more points is incremental improvement.
