Europe's Antipiracy Proposal Draws Criticism
By PAUL MELLER
Published: October 20, 2003
BRUSSELS, Oct. 19 - In an effort to fight product counterfeiting and piracy, the European Union is preparing to enact a sweeping intellectual property law that critics say is ill-conceived and tilted heavily in favor of copyright and patent holders.
The proposal would go far beyond existing laws in Europe and the United States by classifying copyright violations and patent infringements, even some unwitting ones, as crimes punishable by prison terms.

Lawyers who have studied a draft of the proposed law say that not only could a teenager who downloaded a music file be sent to jail under it; so too could managers of the Internet service provider that the teenager happened to use, whether they knew what the teenager was doing or not.
The proposed law would also make it easier for drug manufacturers to forestall generic competition by effectively stretching the duration of their patents, the critics say, and even the makers of replacement auto parts could face prosecution if they sell their wares to consumers.
Backers of the proposed law, which would replace a patchwork of regulations in the union's 15 member countries, include influential European Union officials like Frits Bolkestein, the union's commissioner for internal markets, whose department drafted the proposed law, and Janelly Fourtou, the French member of the European Parliament who is in charge of leading the debate on it.
Mr. Bolkestein said in an interview last month that criminal penalties, which are rarely invoked in European laws, were necessary in this case "because the issue of counterfeiting is becoming overwhelming in importance."
Major corporations in three industries that suffer the most from counterfeiting - music, films and computer software - have combined their lobbying to try to make the proposed law as tough and far-reaching as possible. Even so, when Mr. Bolkestein unveiled the commission's proposed draft in January, trade associations from the three industries issued a joint statement saying that the commission had "failed to introduce urgently needed measures to hold back the epidemic of counterfeiting."
Opposition to the new law was slow to develop but is gaining momentum. Companies like Nokia, the BT Group, and even Microsoft, itself a major victim of software piracy, have called the proposed law excessive and have warned that it could crush technical innovation.
No one on either side of the debate doubts that product counterfeiting is a major problem. The European Commission estimates that it cost the union 8 billion euros ($9.3 billion) a year in lost economic output from 1998 to 2001. Industry groups say that up to two-thirds of all software in use in Central and Eastern Europe is pirated and that one out of three music CD's sold worldwide is counterfeit.
There is a broad consensus here that a Europewide enforcement law is needed because so much of the illegal activity crosses national boundaries. But there is less agreement on what the law should cover.
The proposal before the European Parliament is broad, going beyond movies, music and software to take in all types of intellectual property including patents, copyrights, trademarks and registered designs.
Critics say that such a sweeping law far exceeds what is needed to combat piracy and would criminalize innocent conduct in a number of situations that cannot reasonably be called counterfeiting.
For example, designers at rival technology companies race to match and improve on each other's work, and must make business decisions every day about the subtle line separating permissible innovation from patent infringement. If crossing that line is made a crime instead of just a civil matter, critics like Nokia say, companies will become much more timid in the laboratory.
"It is vitally important that this directive strike the right balance between protecting the interests of right holders without unfairly impeding others from competing," said Tim Frain, director of intellectual property at Nokia.
Greg Perry, director general of the European Generic Medicines Association, said the proposed law would give the big drug companies "the best tool they could have ever wished for" to fight off generics.
By forcing makers of generic drugs to win court permission to bring their versions to market, the big patented-drug makers "could use this proposed law to extend their monopoly by stretching their patent a further 18 months or so beyond its expiry date," Mr. Perry said. "We agree that patents should be respected, but we can't support what would end up allowing for an abuse of the legal system to prevent legitimate competition."

Ms. Fourtou, the Parliament member shepherding the proposed law through debate, said in an interview that she had begun to see merit in leaving patents out of it, because "the issue of patents is so complex."
Last month, a debate on another proposed law on the patentability of software provoked one of the bitterest lobbying battles the Parliament had ever seen, according to several members. Ms. Fourtou said she did not want to see the enforcement law bog down in the same way.
"We are not in a rush, but we'd like this directive agreed before the union takes in the new members from Eastern Europe," she said. She said she also wanted to see the law enacted before parliamentary elections next summer. "I may not be here after the elections," she said.
While she is willing to narrow the proposed law to exclude patents, Ms. Fourtou is trying to expand its reach over copyrights, and in doing so she has drawn some criticism for a perceived conflict of interest.
The commission's original draft limited criminal penalties to those who violate copyrights "for commercial purposes" - language that would exclude consumers swapping music files.
But Ms. Fourtou has struck that limitation from the amended text of the proposed law. "In this sense, the scope of the directive is too narrow," she said. "Even if you aren't downloading music for profit, you still are having a very negative effect on authors and musicians. Even a young boy who does it innocently causes an economic countereffect.
"The Internet is a new way of living for young people," she continued. "It would be very good to send out a message to them, teach them right from wrong."
Ms. Fourtou said the change also brought the proposed law into line with World Trade Organization agreements on intellectual property and with "the wishes of a large number of professionals," referring mainly to the record industry.
One of the world's largest record companies is owned by Vivendi Universal, a French conglomerate whose chief executive is Ms. Fourtou's husband, Jean-René Fourtou.
Ms. Fourtou said that when she was given charge of the proposed law in March, neither she nor her colleagues in Parliament saw her husband's job as a reason for her to recuse herself. "There was a plenary session of the Parliament in July last year," when Mr. Fourtou took the post at Vivendi, she said. "My colleagues all saw his name and his photo in the newspapers. It was not a problem for them. My conscience doesn't have a problem with this."
Some lawyers and legal experts say that, whether it was influenced by her husband's position or not, Ms. Fourtou's amendment would give rights holders too much power.
William Cornish, a professor at Cambridge University, and Josef Drexl, Reto Hilty and Annetee Kur from the Max Planck Institute in Germany criticized lawmakers in a statement for rushing through a disproportionate bill tailored too closely to the wishes of lobbyists.
"Haste and political pressure from interest groups do not make for good counsel when it comes to regulating complex and sensitive fields like that of sanctions and procedural measures for I.P. protection," they wrote.
Thomas Vinje, a partner in the Brussels law firm Morrison & Foerster who shares the concerns expressed by the academics, said Ms. Fourtou's amendments made a bad proposal worse. "She is putting a dangerous weapon in the hands of, among others, the big record companies," he said.
Internet service providers worry about being caught between the proposed law and other European Union rules on data privacy. A provision of the enforcement bill would subject them to criminal sanctions if they failed to provide information to copyright holders about subscribers who may be infringing their rights.
"The balance between privacy of subscribers and the duty to cooperate with right holders seeking to protect their intellectual property that was reached in the e-commerce directive could be changed by this directive," said Tilmann Kupfer, British Telecom's European regulatory manager.
Mr. Bolkestein, the European commissioner responsible for the proposed law, said in an interview in September that he was not aware of concerns that it could trip up legitimate businesses, and said his staff would look into them. Three weeks later, his spokesman, Jonathan Todd, said the commission stood by the draft it presented in January.
"The directive changes nothing regarding the definition of rights, whether they be patent rights, copyright or any other kind of right," Mr. Todd said. "All this changes is the penalties."
Nicolas Regnault n'a jamais dis qu'il testait son programme sur un linux 64 bits. Maintenant, je comprends mieux. Il a compilé sont programme en 64 bits.
Ce qu'ils font est encore 100% légal. Pour combien de temps ?
M'enfin, c'est ce genre d'initiative "limite" qui rende chaque jour plus ridicule et plus extrémiste les actions de la RIAA. Et oui, c'est un bien car cela ne peut que leur péter à la figure.
Pour un programme de calcul numerique multithreads recompile ne tirant pas partie du 64 bits, l'augmentation des performances allait jusqu'a 20% (uniquement grace aux registres supplementaires).
Mmmh. Cela se contredis. Je sais qu'il y a 3 modes dans le processeurs (de mémoire). Genre le mode x86 normal, un mode un peu étendu qui ne nécessite pas de support de l'OS et un mode qui nécessite un support de l'OS.
L'utilisation de plus de registrse nécessite un support de l'os pour être sauvegardé lors du changement de tâche. Donc y'a un truc...
"Quand je repense à cette personne qui me parlait de ses mâles amis qui étaient un peu condescendants à l'égard des non codeuses qui ne pouvaient apporter leur ecôt au logiciel libre, je me dis que le logiciel libre traîne aussi un sacré ramassis de gros cons de machos.[...] C'est pour ça que la première contribution d'une personne dans un projet logiciel devrait être d'apporter un peu de bonne humeur.
Dans la série, je n'ai strictement aucune idée du travail que représente une distrib mais je crache dessus pour faire intaigriste redresseurs de tord....
Pour rajouter ce que dise les autres, les cpu actuelles sont out-of-order. Le cpu analyse le flot des 23 à 128 µinstructions suivante (qui correspond de 1 à "plusieurs" instruction asm). Il peut ensuite plus ou moins changer l'ordre d'execution des instructions en faisant du renommage de registres. Le nombre d'unité varie selon les cpu, 2 alu, 1 fpu, 1 Load&store unit, 1 ou 2 unité vectoriel... avec des latences différentes plus ou moins masqué par le réordonnancement des instructions (mulitplication avec un thoughput de 1 mais une latence de 3), etc...
mmh, je crois que tu te trompes les C68xxx en version flottante tourne à qq centaines de megahertz avec 2 unité Mac pas 64...
(TI utilise un vliw à 8 instructions, ils font donc l'opération 8x la fréquence or cela ne correspond pas à grand chose)
Par contre, si on prends le pentium 4 à 3.2 Ghz qui dispose d'une FPU SSE qui manipule 4 donnés 32 bits. On obtient 3.2*4 = 12.8 Gflop à doubler si jamais le P4 dipose d'une unité SSE MAC (j'ai la flemme de vérifier).
