Perfect 10 v. CCBill: “direct financial benefit” means infringing material must draw users, says Ninth Circuit

(Source: http://blogs.zdnet.com/Howell/?p=119) Posted by Denise Howell @ 1:51 am April 13th, 2007 Late last month, the Ninth Circuit Court of Appeals came out with an important decision, Perfect 10 v. CCBill (PDF), that required it to interpret and apply both the Digital Millenium Copyright Act and Section 230 of the Communications Decency Act — two of the most important U.S. provisions governing conduct on the Live Web. Jason Schultz, Professor Goldman, and Joe Gratz all have good summaries of the details. First, see Jason's rundown of the parties and facts of the case: Background: Perfect 10 publishes adult entertainment magazines and websites. Many third-party websites post Perfect 10 images without permission. CCBill et al provide hosting and credit card services to those sites. Perfect 10 sued CCBill et al. for assisting in the infringement of their copyrights and associated state claims, such as violating the rights of publicity of Perfect 10 models. CCBill raised, among other defenses, the DMCA Safe Harbors and Section 230 of the CDA. Next, there's a lot of meat to the opinion and I encourage you to check out all three of the discussions linked above. But the most interesting part of the decision to me, particularly in the context of the pending Viacom v. YouTube suit, is the court's take on what constitutes a "direct financial benefit" sufficient to preclude a defendant's successful invocation of the DMCA's safe harbor language. Once again from Jason: The Court held that a provider falls outside the protections of 512(c) if they receive "direct financial benefit" from infringing conduct, and that this term should be interpreted consistent with the "similarly-worded common law standard for vicarious copyright liability." The Court then went on to state that the relevant inquiry was "whether the infringing activity constitutes a draw for subscribers, not just an added benefit." Since CWIE (the hosting co-defendant) hosted sites for a fee unrelated to the amount of infringing material, the court found this did not qualify as a direct financial benefit. The "direct financial benefit" exemption is one of the most crucial legal points at issue in Viacom v. YouTube, and here we have the Ninth Circuit saying that if the presence of infringing material is merely an "added benefit" and not a primary draw, a defendant should be immune under the DMCA from liability for the infringing acts of others. As a practical matter, this requires parties and courts to classify and quantify the role of the infringing material, and thus imports a Sony v. Universal/substantial noninfringing use-esque anlaysis into interpreting and applying the DMCA. Advantage YouTube/Google — though the Second Circuit (where Viacom v. YouTube is pending) is well known for departing from the reasoning of the Ninth. There's much more to tease out of the decision. Professor Goldman wraps it up as follows: This Ninth Circuit panel clearly understood the dangers that copyright and publicity rights lawsuits pose to Internet intermediaries, and they took a number of useful steps to push back on a very aggressive plaintiff's novel but expansive theories. Kudos to them. But with two other Perfect 10 cases pending with the Ninth Circuit, I strongly suspect that the most interesting and powerful aspects of this ruling soon will be reshaped by the subsequent opinions. http://lawgeek.typepad.com/lawgeek/2007/03/perfect_10_v_cc.html http://blog.ericgoldman.org/archives/2007/03/ninth_circuit_o.htm http://www.joegratz.net/archives/2007/03/30/more-on-perfect-10-v-ccbill/ http://www4.law.cornell.edu/uscode/html/uscode17/usc_sec_17_00000512----000-.html http://en.wikipedia.org/wiki/Section_230_of_the_Communications_Decency_Act http://en.wikipedia.org/wiki/Sony_Corp._v._Universal_City_Studios

More Research Shows How The Fashion Industry Is Helped By The Lack Of Intellectual Property Rights

from Techdirt by Mike Back in 2003, we mentioned an article that compared the entertainment industry to the fashion industry, noting that even though there was no intellectual property protections over clothing design and copying was rampant, the fashion industry was thriving. This shouldn't come as a surprise, really. After all, without the artificial protectionism, the fashion designers are forced to continually compete by continually innovating and always trying to come out with the latest and greatest design. Even though others copy, there's tremendous value in being the first, or being the "big name" in the industry. The article included this fantastic quote: "Ideas arise, evolve through collaboration, gain currency through exposure, mutate in new directions, and diffuse through imitation. The constant borrowing, repurposing, and transformation of prior work are as integral to creativity in music and film as they are to fashion." In 2005, the NY Times wrote a similar article, but warned that the fashion industry was moving in the wrong direction, as lazy designers who didn't want to compete and wanted to rest on their laurels had started pushing for new intellectual property over their designs. Late last year, the calls for such protectionism grew even stronger -- though, the reasoning doesn't make any sense. The entire point of intellectual property protections is to create incentives for a market. If that market is already thriving, why do you need to add new incentives? The real reason is that it's not to provide incentives. It's a way for successful players to keep making money without continuing to innovate -- which is simply bad for society. The NY Times is taking another look at this issue, this time in a piece written by well-known economist Hal Varian, who points to a recent study that doesn't just note that the fashion industry has thrived without intellectual property protection, but notes that a big part of the reason it has thrived is because of the lack of IP. In other words, if those pushing for those new IP rights get them, the end result will likely be harmful to the overall fashion industry. Again, this shouldn't be surprising, as removing protectionist policies tends to increase competition and the size of the addressable market, but it's certainly a good example to point to when people insist that things like the music industry wouldn't exist without copyright protection.

Buffalo joins Hitachi in the 1TB HDD club

from Engadget by Evan Blass Perpendicular magnetic recording has brought us storage densities beyond our wildest dreams (well, anything above 640KB is pretty amazing, actually), with Buffalo today joining Hitachi in the exclusive, highly-sought after 1TB 3.5-inch hard drive club. Besides the now-legendary 7K1000, consumers will soon have the chance to pick up a nearly-1,024GB platter known as the almost-impossible-to-remember HD-H1.0TFBS2/3G, which features the same 7200 RPM / 3.0Gbps speeds that we've become accustomed to. Japan will see this one first -- sometime around the end of the month -- for about ¥60,165, so expect an eventual street price of under $500 when these finally spin their way stateside. As for us, we're gonna hold off for the time being, because surely this flood of terabytes means that 1PB models are right around the corner.

Nanogenerator Provides Continuous Electrical Power

Device harvests energy from the environment to provide direct current

Atlanta (April 5, 2007) — Researchers have demonstrated a prototype nanometer-scale generator that produces continuous direct-current electricity by harvesting mechanical energy from such environmental sources as ultrasonic waves, mechanical vibration or blood flow.

Based on arrays of vertically-aligned zinc oxide nanowires that move inside a novel “zig-zag” plate electrode, the nanogenerators could provide a new way to power nanoscale devices without batteries or other external power sources. “This is a major step toward a portable, adaptable and cost-effective technology for powering nanoscale devices,” said Zhong Lin Wang, Regents’ Professor in the School of Materials Science and Engineering at the Georgia Institute of Technology. “There has been a lot of interest in making nanodevices, but we have tended not to think about how to power them. Our nanogenerator allows us to harvest or recycle energy from many sources to power these devices.” Details of the nanogenerator are reported in the April 6 issue of the journal Science. The research was sponsored by the Defense Advanced Research Projects Agency (DARPA), the National Science Foundation (NSF), and the Emory-Georgia Tech Center of Cancer Nanotechnology Excellence. The nanogenerators take advantage of the unique coupled piezoelectric and semiconducting properties of zinc oxide nanostructures, which produce small electrical charges when they are flexed. Fabrication begins with growing an array of vertically-aligned nanowires approximately a half-micron apart on gallium arsenide, sapphire or a flexible polymer substrate. A layer of zinc oxide is grown on top of substrate to collect the current. The researchers also fabricate silicon “zig-zag” electrodes, which contain thousands of nanometer-scale tips made conductive by a platinum coating.

The electrode is then lowered on top of the nanowire array, leaving just enough space so that a significant number of the nanowires are free to flex within the gaps created by the tips. Moved by mechanical energy such as waves or vibration, the nanowires periodically contact the tips, transferring their electrical charges. By capturing the tiny amounts of current produced by hundreds of nanowires kept in motion, the generators produce a direct current output in the nano-Ampere range. Wang and his group members Xudong Wang, Jinhui Song and Jin Liu expect that with optimization, their nanogenerator could produce as much as 4 watts per cubic centimeter – based on a calculation for a single nanowire. That would be enough to power a broad range of nanometer-scale defense, environmental and biomedical applications, including biosensors implanted in the body, environmental monitors – and even nanoscale robots. Nearly a year ago, in the April 14, 2006 issue of the journal Science, Wang’s research team announced the concept behind the nanogenerators. At that time, the nanogenerator could harvest power from just one nanowire at a time by dragging the tip of an atomic force microscope (AFM) over it. Made of platinum-coated silicon, the tip served as a Schottky barrier, helping accumulate and preserve the electrical charge as the nanowire flexed – and ensuring that the current flowed in one direction. With its multiple conducting tips similar to those of an AFM, the new zig-zag electrode serves as a Schottky barrier to hundreds or thousands of wires simultaneously, harvesting energy from the nanowire arrays. “Producing the top electrode as a single assembly sets the stage for scaling up this technology,” Wang said. “We can now see the steps involved in moving forward to a device that can power real nanometer-scale applications.”

Before that happens, additional development will be needed to optimize current production. For instance, though nanowires in the arrays can be grown to approximately the same length – about one micron – there is some variation. Wires that are too short cannot touch the electrode to produce current, while wires that are too long cannot flex to produce electrical charge. “We need to be able to better control the growth, density and uniformity of the wires,” Wang said. “We believe we can make as many as millions or even billions of nanowires produce current simultaneously. That will allow us to optimize operation of the nanogenerator.” In their lab, the researchers aimed an ultrasound source at their nanogenerator to measure current output over slightly more than an hour. Though there is some fluctuation in output, the current flow was continuous as long as the ultrasonic generator was operating, Wang said. To rule out other sources of the current measured, the researchers substituted carbon nanotubes – which are not piezoelectric – for the zinc oxide nanowires, and used a top electrode that was flat. In both cases, the resulting devices did not produce current. Providing power for nanometer-scale devices has long been a challenge. Batteries and other traditional sources are too large, and tend to negate the size advantages of nanodevices. And since batteries contain toxic materials such as lithium and cadmium, they cannot be implanted into the body as part of biomedical applications. Because zinc oxide is non-toxic and compatible with the body, the new nanogenerators could be integrated into implantable biomedical devices to wirelessly measure blood flow and blood pressure within the body. And they could also find more ordinary applications. “If you had a device like this in your shoes when you walked, you would be able to generate your own small current to power small electronics,” Wang noted. “Anything that makes the nanowires move within the generator can be used for generating power. Very little force is required to move them.” Research News & Publications Office Georgia Institute of Technology 75 Fifth Street, N.W., Suite 100 Atlanta, Georgia 30308 USA Media Relations Contact: John Toon (404-894-6986); E-mail (jtoon@gatech.edu).
