Breakpoints have now been patented

An anonymous reader noted that apparently Breakpoints have now been patented. From the link "A method for debugging including the steps of receiving code having a software breakpoint function therein, running the code for the purpose of debugging, monitoring the code to detect the presence of the software breakpoint function, recognizing the software breakpoint function, determining an action to be performed based on the software breakpoint function, and implementing the action. The present invention also includes an apparatus for implementing the method for debugging and a medium embodying a program of instructions for execution by a device to perform the method for debugging."

I think this is a bit different

[AKAImBatman]

I'm not up on my patent-ese, but I think this is describing a specific type of breakpoint technology based on virtual functions. Since we've been talking about Javascript so much lately, and it's so easy to do virtual functions in JS, here's an example in JS code:

Debugger.breakPoint = function()
{
//do nothing
};

Now if you put the function in your code, nothing happens:

Debugger.breakPoint();

But if you have the debugger initialized, it will replace the virtual function like this:

Debugger.breakPoint = function()
{
    Debugger.runDebuggerAndStopTheWorld();
};

Thus you end up with software breakpoints that can trigger the debugger based on optional listeners. At least, that's how I understand it. I could be wrong about the actual implementation.

are you kidding?

"Free patents online" is a service that lets you search for patents on-line for free; the patents themselves aren't "free".

I just patented CODE WITHOUT COMMENTS

to prevent horrors like OP. Did you notice how the "free(b)" call was after an unconditional return? Somebody didn't.

Yeah, except that debugging, breakpoints, and "virtual functions" or closures, interpreted code, or whatnot have been around for so long, that there is essentially nothing new under the sun. Smalltalk implementations were able to call into the debugger through an assert-like mechanism. You could then enter the debugger, change values around, and continue execution. Made things much easier when you were in the middle of a multi-day simulation test run and hit a problem. You could note the problem, fix it, and continue. Various Lisp, Scheme, ProLog and so forth variants have done some very neat things with debugging support through assertions, exceptions, traps, and all kinds of mechanisms. Essentially, any time you have an interpretive runtime, people play with different ways to do debugging.

Another way to look at it is that many runtimes will automatically enter the debugger on an exception or trap of some kind. An assertion failure generates an exception or trap. Assertions are generally controlled by DEBUG variables of some kind. Viola! Configurable code-side breakpoints. Different languages handle resumption from exceptions in different ways.

The problem is that people who write patents think that the mere act of putting two things together is innovative, even if the first thing is a tool, and the second is a logical extension of the tool's purpose, like adding "on the Internet" to something and calling it an invention. In this case, they did not even bother to see if it was done before, probably because they have no knowledge of languages outside the mainstream.

Re:hardware debugger

[richie2000]

I had a hardware breakpoint debugger in The Final Cartridge II on the Commodore 64. That was, what - 20-25 years ago? This patent was issued last year.

That said, the first 13 claims pertain to software only (curio: the word "software" appears no less than 17 times in the first claim, "hardware" scores a big fat zero). Subsequent claims seem to revolve around a device reading a medium where the debug code is stored, ie RAM, some kind of ROM or even a CD with reader would fit this description.
It's so vaguely stated as to be totally useless. Useless, that is, if someone were to actually use this patent to implement something useful. You know, like the patent system was supposed to do. Very useful if it's to be used to threaten competitors and stifle innovation.

"To promote the progress of science and useful arts", my ass.

Re:Could someone please patent code comments?

[SL Baur]

No that's not what they've patented. They've patented source level debugging with static break points. Apparently the developer litters the source code with SOFTWARE_BREAKPOINT; calls which turn into do-nothing statements if there is no debugger running the code. The target environment appears to be an embedded system like a cellphone.

They have not patented hardware breakpoints, gdb, etc. and a huge advantage of their system is that you could apparently debug and selectively enable/disable breakpoints in a production ROM executable image.

I know noone reads these patents when these kinds of articles go by, this is /., but is it too much to ask that the article submitter or the editor read them first?
