Also, the "injured party" has to have demonstrated an active and consistent defense of their IP. I.e., if lots of folks are doing this and they only come after *you*, then you have a stronger defense. Conversely, if they religiously go after *everyone* known or suspected of this type of "violation", you have a harder time defending yourself. This, IMO, is one of the biggest arguments *against* copyright, patent, etc. "protection" -- the burden falls on the IP holder to defend it.

No, that's not correct - it depends on the type of "IP". If you have a trademark and you don't defend it, you lose the rights to it. But if you have the copyright to something, you keep those rights regardless of how much you fight for it or not. Success in past court cases will often make it easier to win new cases (or to persuade people to settle out of court), but you don't have to litigate or otherwise fight for your rights if you don't want to. The same applies to patents.

The biggest problems are exactly the opposite, especially with patents. The patent holder will sue someone, who then has to pay to defend themselves in court - and if the defendant believes the patent is invalid, the burden of proof is on them to prove it invalid. This means that in many cases, especially with software patents, the innocent defendant in patent cases has to pay high legal costs - it is cheaper for them to pay the protection money.

IANAL either ... ... but unfortunately in the USA, some reverse engineering IS a crime. The DMCA (Digital Millenium Copyright Act) forbids most use cases of reverse engineering encryption/decryption, anti-copying and digital rights management schemes. DMCA contradicts itself, patent law and consumer protection law ... and few aspects of it have been challenged in court despite the law being 15 years old. It has been amended a couple of times, but the result has been that the law has only gotten murkier. Moreover ... and this just happened ... a new bill in Congress is trying to make copyright infringement a punishable crime as opposed to the civil offense it now is. This is very worrisome because it interacts with the more nasty twists of DMCA which make it unclear when, if ever, fair use applies. George

You're missing the point. No one is going to hunt down possible infringers on your behalf. It's a civil issue (in the US). So, *you* have to identify all potential infringers and bring suit against them. And, in the process, put *your* patent's validity on the line (the "accused" can move that your patent is invalid and, if he wins that point, you *lose* that patent protection). You also have to spend time/money to investigate (reverse engineer) the means by which the *suspected* infringement is taking place. I.e., unless your explicit independant claims are infringed, you have no grounds for your case. (I can do the same thing that your patent claims to have invented but do so *differently* and I'm not infringing; the patent examiner's job is to try to get your patent application to be as narrowly focused as possible) I see no real value to modern day patents -- especially with terms like 20+ years. Note, also, that public disclosure of a patentable idea turns it into prior art. Making subsequent patentability a moot point (though in some jurisdictions you may have up to a year to capitalize on this) IMO, the GPL is just as bad as patents. The idea should be to encourage people to *innovate*. Forcing people to share their innovations doesn't really do that -- any more than giving people exclusive use of their innovations! E.g., I use a Berkeley style license on anything that I release...

My point here is that you /don't/ have to hunt down possible infringers. It is only with trademarks that you /have/ to pursue people, and even then it is only if they are "visible". If you make a wheelbarrow, called it an "ipod", and sell a hundred per year, then Apple can and will ignore you, with no harm to their trademark. But if you integrate a music system and sell ten thousand, then Apple /must/ sue you for the protection of their trademark. For other types of "IP", there is /no/ requirement to pursue infringers. It's up to you - if you think it is worth the time and cost, then go for it. If not, then you can send them salesmen or lawyer's letters or just ignore them. It is correct that you will have to invest money if you want to take the infringer to court - and I agree that in an ideal system, only the guilty party would ever have to pay. But for such cases, either party could be guilty - patent trolls are as common as patent infringers. A better system would be to have a cheaper, faster, more technical and less legal arbitration system to have technically competent independent experts decide on copyright and patent disputes. Most issues could be cleared up quickly and at minimal costs (except, of course, for any damages paid by the guilty party), and either side could always appeal to normal civil courts if they disagreed with the judgement.

It's worth distinguishing a bit between different types of IP - trademark cases are usually easy to see one way or the other, because things are out in the open. Copyright abuse is often harder to prove one way or the other. But you seem to be talking mainly about patents, which are the most controversial of the three. I agree that patents are a bigger problem, so we can concentrate on them.
> I see no real value to modern day patents -- especially with > terms like 20+ years. >
I've heard that there is no point in taking out a patent unless your invention is worth $10m - otherwise it's not worth the money suing people. There is a vast amount that is wrong with the patent system we have today, and it is the total antithesis of the original aim of patents. This is most obvious in the world of "software patents" which some countries have, but applies more generally. However, I don't agree with your feelings that it is unfair on the patent holder, who must invest so much to pursue an infringer. It is /equally/ unfair on those who are sued by patent holders when they have not infringed on the patent, or when the patent should be invalidated. It is a terrible system for everyone, except the lawyers.

The GPL is an excellent (though not perfect) choice of licence for many types of software - but it is not appropriate for all types. Very roughly speaking, it is a good choice for software that people will use as programs, but a poor choice for software that people will use as part of their own programs (then something like a BSD or MPL style is normally better). The GPL forces the software to remain free - sometimes the "free" part of that phrase is the best part, sometimes the "forces" part is the worst part. So the GPL is a good choice for gcc - there is no reason why anyone would want to take the source code of gcc and hide it away unless they wanted to sell some or all of it as their own proprietary code. The GPL provides legal protection against it. But on the other hand, the GPL is a poor choice for the gnu readline library - free software fanatics choose the GPL for readline as a way to try to force people to use GPL for their software. The result is that lots of programs that could benefit from using the library, cannot use it because of the license - and that there are several "competing" libraries around with different developer-friendly licenses (mostly BSD-style). When the GPL restricts /your/ freedom to choose a license for /your/ code, then it is non-free and a bad choice. But when you /want/ your code to be free, then it is a good choice to help keep it free.

Perhaps my reference to Micky Mouse laws was too subtle, but that's what I meant. Apparently, the DMCA /does/ allow for reverse engineering for compatibility purposes, and for security issues, amongst its various exceptions.

The DMCA contradicts most things, especially common sense and the basic human perception of fairness. Remember, courts and laws are a /legal/ system, not a /justice/ system - and the law has always been heavily biased towards who has the most money. (This is not just a criticism of the USA, though it is perhaps more obvious there than in most countries - it extends back at least as far as Roman times.)

What I always find difficult to understand is how this sort of thing can happen in a democracy. You are supposed to be governed by the people, for the people. It is unlikely that you will find a single living person in the USA above the age of 5 who has never infringed on copyright - with the huge majority doing so regularly and knowingly. So this law would turn the entire population into criminals. Have you ever taped a program off the tele, and watched it more than once? Or kept the recording for more than 30 days? Go directly to jail, do not pass go and do not collect $200.

Frivolous software patents are essentially a self correcting problem. They have a limited life and most of them have already died. The whole issue of IP protection is to create an incentive for people and companies to risk a disproportionate amount of resources to the potential individual gain in the development of new ideas. A large percentage of these developments never produce enough revenue to pay development costs. Something is needed to to protect the ideas that are truly unique and useful. Real technical innovation has slowed down a lot in the last decade. Regards walter.. -- Walter Banks Byte Craft Limited http://www.bytecraft.com

If only that were true! There are huge numbers of software patents around, and /very/ few of them would ever have been granted if the rules were followed - to get a patent on something, it must be an /invention/ that is /new/, /non-obvious/, and /useful/. Many people feel that a purely software solution is not an "invention" - thus all pure software patents are invalid and frivolous. Even if you allow that a software algorithm is an "invention", the majority of granted patents are not new, or are at least very similar to existing software or methods, and a very large proportion are obvious to experts in the field. And even in cases where the patent is clearly frivolous beyond any reasonable doubt, if the owner sues an "infringer", it can still be cheaper for the victim to settle out of court. And the victim, being (typically) bound by law to put their shareholders profits above their own sense of morality and justice, will do exactly that. Then when the patent owner attacks the next "infringer", they can point to the previous settlement as extra evidence. So frivolous patents are a self-reinforcing problem, not self-correcting. Case in point - if what I've read is correct, Microsoft makes more profit from Android phones than from Windows 7 phones, because manufacturers like HTC must pay them royalties for the use of patents that are "infringed" by Android (and the Linux kernel in particular). They have not revealed exactly which patents are covered, but they are almost certainly mostly frivolous (MS was awarded a patent on the "PgUp" and "PgDn" keys three years ago, as an example).

Oh, I agree on the principle behind the original aim of patents - it's a good idea to have a system that rewards innovation, inventiveness and people willing to take risks for a good idea. It was designed to allow small inventors to have a good idea and let big manufacturers mass-produce the inventions for the public good, while letting the inventor get a solid share of the profits. The trouble is that the modern patent system, especially in more modern areas like software, simply does not do that. It fails in almost every conceivable way, and is a very big reason why technical innovation has slowed down. When technical companies spend more on lawyers than on engineers, the system is unrecoverably broken. mvh., David

<frown> I guess it depends on what you consider "frivolous". Part of the problem (IMO) is that engineers (except those who seem to delight in listing patents on their CV's) look at most patents and consider them "obvious" -- which contradicts the idea of "innovative" (in our minds). So, to an engineer, most patents are "a joke". However, that doesn't stop a patent from being *granted* Hint: patent examiners are civil servants and this is just a *job* to them. they may not even have any real technical proficiency in the areas for which they are critiquing the patent applications! (and, from speaking with one, there is apparently a lot of nonsense "mechanism" involved in the process that rewards them for "shuffling paper" instead of "doing the right job")

While that seems irrational on the face of it, note that those developments must obviously add value to the products to *justify* those costs else they simply wouldn't be undertaken. You don't build a *different* mousetrap unless it will also be a *better* mousetrap and, presumably, generate more revenue, recognition, etc. for you!

+42 The problem is the profit-and-loss side of the equation. It's easy to encourage innovation. Get 6 "motivated" engineers in a room and have them see who can one-up the others. It won't take long for a "better" (though perhaps not "best") idea to surface. And, they'll probably *enjoy* the "competition"! But, in the business world, "motivate" is spelled with two $'s! Which means there has to be some reckoning at the end of the day to square up accounts. Businesses tend to be greedy and self-serving (that's not a criticism, just a statement of fact). They aren't inclined to discard a financial/business advantage if they don't have to! (can someone explain why CompuServe so stodgily held onto it's "ownership" of the GIF format? Did they even have any real corporate existence anymore?? Or, was this their "sole asset"?) Businesses expect to be "reimbursed" for their innovations in terms of *profits*. :> Coming up with a practical scheme that addresses innovation, protection and dissemination is what patents were *supposed* to do. Unfortunately, times have changed so much in the decades since their inception that the time scales just don't make sense! They now *hinder* (IMO) more than *help*.

Well, I happen to be related to two IP attorneys and count several others as friends ... I considered going into IP law myself at one point. IP attorneys are /required/ to have a science or engineering background so they tend to be much more reasonable about things. Every one of them considers the DMCA a crock of $%^& and would love to have a multi-million contra case to try.

Your first mistake is thinking you live in a democracy ... you don't (no matter where you live). I can't think of a single nation that actually is a democracy. There are republics, federated republics, constitutional monarchies, actual monarchies, dictatorships, theocracies, and some of the apparent dictatorships might really be oligarchies (it's hard to tell the difference sometimes) ... but AFAICS, no democracies. Some countries may embrace classic democratic elements such as public elections, but that doesn't make them democracies. In a democracy every voice is equal and every issue that affects the public is put to collective vote. Any form of government that involves representation rather than direct public involvement is not a democracy. The fact that the U.S. is NOT a democracy is enshrined in the Pledge of Allegience, which reads: "... and to the Republic, for which it stands ...". The U.S. is, in fact, an example of a federated republic. For decades now, schools have been misteaching and misleading students into believing they live in a democracy. I normally don't subscribe to conspiracy theory, but in this matter I have come to believe that this particular misteaching is by design ... the misconception is far too widespread to be the result of students misunderstanding their civics lessons. [YMMV and I really don't care to debate it ... at least not here.]

Actually, recording television and radio for the purpose of "time-shifting" is expressly PERMITTED by law regardless of the idiotic warnings you hear during some broadcasts. That was settled by the US Supreme Court back in the 1970s and subsequently was written into copyright law. I don't have the cite handy, but time-shifting falls under fair use and DMCA did change existing law regarding it. As you mentioned above, you must destroy a "time-shift" recording within 30 days and you aren't permitted to profit in any way from it. You can, however, watch it as many times as you wish within the time limit. George
