Well, so are corporate patent laywers then:  There is near panic in
several of the big patent pools, because they also read Bilski along
the lines I laid out.

The Bilski ruling is indeed narrow, but there are more junk patents
in that a narrow corridor than you probably imagine.  One unofficial
estimate, from an insider, is that IBM alone lost "at least 1000,
possibly 2000 patents to Bilski".

The only reason you have not heard the full roar on this, is that
lawyers treasure their vacation.

[time-nuts] HP 5335A and HP-IB (GP-IB)

2010-08-02 Thread Joe Geller
Without making any judgments about whether there should be business method or 
software patents, I think that advocates are reading more into Bilski than is 
actually there.  

The link to the opinion was posted earlier, the opinion is relatively short and 
generally readable by non-attorneys.  Remember that comments in concurring 
opinions and dissenting opinions are informative, but not law.  It is probably 
better to begin by reading the actual opinion, and only then to look to the 
comments and analysis on web.  The most significant section is the "Opinion of 
the Supreme Court" written by Justice Kennedy which starts at page 5 and ends 
on 
page 20, a relatively quick read.

Bilski was addressing the question of a business method at the level of "patent 
eligibility".  Patent eligibility is a first question at the "door step" of the 
patent process, before an Examiner begins to consider whether the claims of a 
patent application are novel or non-obvious.

The Supreme court rejected the business method claims in Bilski as not 
patentable since the claims are in the opinion of the court, directed towards 
an 
abstract idea.  An abstract idea was not patentable under U.S. Patent law 
before 
Bilski, this is not new law.

The Supreme Court went on to say that Bilski is to be taken as a "narrow" 
decision and that they were not addressing any question of what constitutes a 
patentable “process,”.  "Today, the Court once again declines to impose 
limitations on the Patent Act that are inconsistent with the Act’s text."

A business patent is different than a software patent.  The Supreme court did 
not make any holding on software patents, nor did they state any new law 
regarding the patentability (the patent eligible question) of a business method 
patent.

One very interesting aspect of the decision is that the "machine or 
transformation" test is no longer the only test for evaluating if these classes 
of patents are patent eligible (this is new).  It is unclear if this aspect of 
the opinion makes the patent eligible field wider (some think yes) or narrower.

The terms "Business Method" and "abstract idea" are not well defined.  The 
extent of the "machine or transformation test" (still valid, just no longer an 
exclusive test) is also not well defined.

Regarding the current state of U.S. Patent law, just below the precedential 
weight of the Supreme court is the CAFC, the Court of Appeals for the Federal 
Circuit.  The PTO generally follows holdings of the CAFC unless overturned by 
the Supreme Court or new laws of Congress.

For now, there are no changes regarding software patents (perhaps influenced 
though by what evolves regarding the "machine or transformation test").  The 
Supreme Court specifically stated that they were not offering a new test: "In 
disapproving an exclusive machine-or-transformation test, we by no means 
foreclose the Federal Circuit’s development of other limiting criteria that 
further the purposes of the Patent Act and are not inconsistent with its text". 
 
Probably more guidance will come from future CAFC cases.

Actions by the PTO Appeals board, while possibly indicative of some new law to 
come, usually many years later, in and of themselves are very case specific 
decisions and highly unlikely to change the current patent law.  Also, I do not 
believe there is currently any simple or distinct test as to what software 
patents are "patent eligible".  Generally some coupling to a machine or 
apparatus is more likely be taken as patent eligible, however that is not a 
legal test.  Also, more likely to survive is an algorithm that performs some 
action, such as steering a ship, for example, but again there is no distinct 
yes 
or no test.

Re: [time-nuts] 74AC175PC

2010-08-02 Thread Mike Feher
Thanks Rex - As an old time ham and engineer, the only code I know is
Fortran and Basic. When I used to design digital stuff for a living,
everything was hard wired, no code. For FFTs, IIR and FIR digital filters
the coefficients were also hard wired. Heck, my first digital filter design
used serial arithmetic, with shift registers to implement the z^1. I was
able to figure out what H(s) we needed and convert it to an H(z) for a
specific filter configuration, but other than for the simulations, the
implementation was hard wired. This was in the early 70's. The neatest part
was to see the implementation exactly match the simulation. Then I went into
RF for a living and am totally naïve about all this source code stuff for
PICs and otherwise. So, sounds like this is something I should also invest
in. If the provider is reading this, please let me know what to do to order
the kit. Thanks & Regards - Mike

Hi

The boxes all seem to go into survey, complete it and then happily lock up.
One seems to have a broken "lock" LED, but z38xx shows it running fine. 

If I understand you correctly, there is no real "write to eeprom" command.
It's just a matter of turning off the survey at boot function.

Hi Bob,
   I have a Z3801A and I am not sure whether the SCIP commands are the 
same as for the Z3805A. There must be some differences related to the 
channel numbers and serial post configuration at least I would expect. I 
think the following apply.

   You need to not only be able to provide a position, as was suggested, 
or from a survey, but to also prevent site survey from starting up at 
power on. Survey at start is default, at least on the Z3801A, and from 
what you say, I suspect your box does the same.
If a position is specified, or the survey completes OK, the unit should 
go to position hold mode automatically.
  To check.
:GPS:POSition:HOLD:STATe?

To specify what startup mode you want
:GPS:POSition:SURVey:STATe:POWerup ON or OFFON forces a survey.
  to check
:GPS:POSition:SURVey:STATe:POWerup?

If it is turned off the receiver will use the last valid position it 
has. This might be the default , (Korea) if the eprom is shot.

hope that helps,
Mike

Yes, I can but it will be toward the end of the week before I can ship them as 
they are in a different location. I'm still shipping boards as they are with 
me. 
If anyone wants the chips please email me off  list or paypal me at 
stanley_reyno...@yahoo.com . I also have all the other parts but will keep 
shipping boards as my first priority. I have some 10Mhz 20PPM osc  and a 80Mhz 
100PPM osc. The 80Mhz I think they would be good for calibration of interlopers 
but not measuring. I can program the Pic chips and test them in my board.

Do not expect parts orders to be filled fast till I see what demand is like. 

I would like to remind everyone that this design was a free gift to time nuts 
by 
Richard McCorkle. My only connection is to provide the boards at low cost, some 
emails to me indicate some confusion that I'm more connected than I am.

Others on the list have provided help with the boards and advice to me on my 
projects so I will try to help all complete this project.

Basically what this patent is saying is that if you give the controller

call back the function when it is ready, and your controller is GPIB,
you owe NI royalties.

You have got to be joking!

Bonjour Loïc,

 I am very happy with the 53131 and 53132 that I have (the latter
have 150ps resolution, as opposed to the 500ps resolution of the
'131). As well as a GPIB port, they also have a simple D9 serial port,
and can very easily be configured to output each reading down the
serial port, for easy viewing using something like Hyperterm (in
Windows), and subsequent capture to file for later analysis.  Expect
to pay up to €1000 for these.  They do, however, have a small fan that
runs all the time.  This can be slightly irritating in a quiet home
environment, but is lost in the noise of the air-conditioning at work
:-)

Pretty fast after the Bilski ruling, the patent appeals board took a HP 
software patent which was in front of them on "prior arts"
grounds, turned it around send it back down with "according to SCOTUS this 
stuff cannot be patented in the first place".

The very brief summary is that the Supreme court ruled that you cannot
patent "a way of hedging energy purchase" or other "purely abstract"
inventions.

In the ruling, which is well worth the read, the judges, together
and individually, are very sceptical of patents which do not cover
tangible stuff, and in particular affirms the day-1 patent-law
principle that "purely abstract" things, like mathematics cannot
be patented.

(http://www.supremecourt.gov/opinions/09pdf/08-964.pdf)

The ruling does not directly address software patents, but it does
raise the barrier considerably with the "purely abstract" part and
several of the separate opinions seem to let it shine though that
they would love to get a pure software patent in front of them, so
they can rule against it.  This also shone through during the
arguments on Bilski.

Needless to say, this is not going to sit quietly with IBM, Microsoft,
Oracle/Sun and so on, which have invested huge sums in their
patent portefolios.

Pretty fast after the Bilski ruling, the patent appeals board took
a HP software patent which was in front of them on "prior arts"
grounds, turned it around send it back down with "according to
SCOTUS this stuff cannot be patented in the first place".

(http://www.groklaw.net/pdf/proudler.pdf)

They probably figured that software patents would end up in front
of the supremes no matter what, so they might as well speed the
process up, by kicking a big company over a patent that was as far
along in the process as possible, to make it happen sooner.

As long as the patent appeals boards ruling stands, all pure software
patents are void.

A good rule of thumb for "pure software patent" is: "If can it run
on any normal computer, like a PC, without special hardware, it
cannot be patented".

The Supreme Court seems, lately, to be doing as much to destroy America
