Pressing Matters: Inserting Indow Windows for Energy Efficiency

October 17th, 2014 by Eric Lane No comments »

Indow Windows (Indow) is a Portland, Oregon, company that has developed energy efficient window inserts.

Indow owns at least one U.S. Patent and a pending patent application covering its storm window technology.  U.S. Patent No. 8,272,178 (’178 Patent) is entitled “Press-fit storm window” and directed to a storm window assembly comprising a transparent panel and tubes or gaskets for insertion into a window frame.

The tube (102) has a hollow interior and a channel groove that connects it to the panel (130).  The tube allows a pressure fit (350, 352, 354) into a window frame.

FIGS. 6(A)-6(C) show a molded tube corner piece which includes parallel plates (605, 615) with a gap (617).  Notch (643) facilitates better coverage and flexibility while find (641) provides improved adhesion and insulation.

FIG. 5 shows the corner piece being inserted into a window frame.

U.S. Patent Application Publication No. 2014/0174006 is a related application (continuation-in-part of a continuation-in-part) owned by Indow, which adds some new material to the original disclosure of the ’178 Patent.

According to the ’178 Patent, the invention is intended to supplement, rather than replace, existing windows:

The windows are not designed to replace existing windows, but rather to supplement them by creating a tight seal between the interior space or exterior space and the existing window.

The invention accomplishes this by creating outward pressure around the edge of the panel:

In one embodiment of the inventive press-fit storm window, a transparent panel of acrylic glass, such as PLEXIGLAS, glass, or other clear rigid material is held in place by the spring action created by a continuous (or partial, conceivably) round gasket (or other spring-like gasket), that creates outward pressure around the entire exterior edge of the clear panel (or the top, left, and right sides). The panel is held securely in place through a combination of this outward pressure and friction.

A press release emailed to me by the company notes that its compression tube requires no mounting hardware or track system.  Significantly, the press release cites a U.S. Department of Energy study which found that installation of Indow Windows in a home in Seattle “led to a more than 20 percent reduction in heating, ventilating and air-conditioning use.”

The windows have gotten some recognition – according to the press release it has won a number of awards including the 2014 Top Product of the Year Award in the Environmental Leader Product & Project Awards.

ECO founder Helps Engineers Become Cleantech Entrepreneurs

October 13th, 2014 by Eric Lane No comments »

Just a quick report on a recent addition to the clean tech start-up community and blogosphere.  It’s called ECO founder, and the company hasn’t developed any exciting technology or new business model.  It provides something much more fundamental.

ECO founder helps engineers with green tech innovations and other budding clean tech entrepreneurs learn the ropes of managing a start-up.  Run by George Gray and based in Los Angeles, ECO founder teaches business and start-up skills via such programs as the 30-Day Challenge and Mr. Gray’s book, Engineer to Founder.

Of course, there is an ECO founder blog, with a variety of posts such as “Learn Key Business Skills Before You Leave Your Engineering Career,” “How to Build a Killer Elevator Pitch,” and “Go-to Market: Six Steps Cleantech Marketing.”

Why is Mr. Gray providing this services for green technicians?  He hopes that ECO founder can help people who don’t have the start-up skills obtain some fundamental skills and be successful:

Most engineers and scientists don’t have the startup skills to launch a clean-tech startup.  ECO founder is here to change that.

Burning Ring of Fire: Greenwashing Case Alleging Fried Solar Panels to Move Forward

October 6th, 2014 by Eric Lane No comments »

In February, three individuals filed a proposed class action lawsuit against BP Solar and Home Depot accusing the solar panel maker and retailer of greenwashing in connection with certain solar panels (see the complaint here).

Plaintiffs Michael Allagas, Arthur Ray, and Brett Mohrman alleged that there is a latent defect in the junction box of the BP solar panels that causes the box to fail and results in a total loss of functionality of the solar panels.

Specifically, the plaintiffs allege that the defect in the junction box and solder joints between connecting cables makes the solder joint overheat, which causes electrical arcing that generates temperatures of 2000-3000 degrees.  According to the plaintiffs, the heat melts the junction box, burns the cables and solar panels, and shatters the glass cover of the panels.

The plaintiffs also alleged that BP’s advertising and marketing materials about the solar panels are false or misleading.

While the northern California federal court hearing the case previously dismissed some of the plaintiffs’ claims, a recent decision denied BP and Home Depot’s motion to dismiss the remaining claims.

The court found the pleadings sufficient to support plaintiffs’ express warranty claims for breach of the express defect and power warranties because they stated that a latent defect existed at the time the product was sold and that they relied upon BP Solar’s power warranty in purchasing the solar panels.

Similarly, the implied warranty claims were held to be sufficient because plaintiffs clearly alleged a latent defect in the solar panels that renders them unmerchantable and unfit for their intended use.

With respect to the advertising and marketing materials, the plaintiffs cited various sweeping representations made by BP Solar, including:

Promises that the solar panels will “drastically reduce or eliminate your electric bills . . . forever,” and will “increase the value of your home.”

A statement that “No other system can operate at a higher level of safety than those offered by BP Solar.”

BP Solar also made some specific representations about the output and life of the solar panels, including product data sheets warranting 80% power output for a 25-year period and a 90% power output for a 12-year period with a 5-year warranty of materials and workmanship.

The court held that plaintiffs’ claims under the Consumer Legal Remedies Act could go forward because the statements include “factual representations” that could be “likely to deceive a reasonable consumer.”  The court concluded:

A reasonable consumer could have relied on these statements as descriptions of the quality and power capabilities of the solar panels.

The court maintained the plaintiffs’ fraud claims because they allege that BP knew of and concealed the defect:

The amended complaint also alleges BP’s knowledge of the latent defect in the solar panels, BP’s concealment of the defect, particular instances when information regarding the defect and risk of fire could have been revealed, and the warranties all three plaintiffs relied upon that failed to include the concealed information.

The court also denied the defendants’ motion to strike the class allegations, but left the door open for BP and Home Depot to contest those upon a subsequent motion by the plaintiffs for class certification.

It’s No Use: Why Chevy’s BOLT Trademark Isn’t (Necessarily) a New Brand

September 24th, 2014 by Eric Lane No comments »

There is some curious eco-mark news to report:  apparently, last month General Motors filed two notable U.S. trademark applications, one for BOLT and the other for CHEVROLET BOLT.

They are Application Nos. 86357513 and 86357523 (BOLT Applications), respectively, and list the goods as “motor land vehicles, namely, automobiles.”

The clean tech and electric vehicle blogosphere was buzzing with speculation as to what this new brand means.  Is GM planning to offer additional EVs, perhaps a new low-cost Chevy Volt, a short-range performance vehicle, or a cool new concept car?  Maybe different battery sizes?

One clue is that the BOLT applications’ goods listing is much broader than the goods in GM’s prior CHEVROLET VOLT trademark registration, which identified “extended range electric automobiles.”  So, contrasted with the VOLT, the BOLT trademark could cover any type of automobile, electric or otherwise.

For now, though, the clean tech blogs had to conclude there is no indication that GM intends to use this new trademark.  Inside EVs proposed that GM might be trying to protect itself from a Chinese ripoff called Bolt.

Gas 2.0 carried this non-use preemptive motive further, noting that:

Car companies are constantly taking out trademarks for names they have no intention of using; it’s just a matter of making sure nobody else uses it either.

While car companies may try to keep potential brand names away from their competitors, there are strict legal limits on the ability to protect a trademark that is not in use.

To fully understand this and to put the BOLT Applications in context, we need a bit more information about the U.S. trademark system.

A U.S. trademark application must have one or more legal bases, i.e., a situation (basis) defined by the federal trademark law, to support the filing.  The available filing bases are (1) actual use of the mark in interstate commerce, (2) a bona fide intent-to-use the mark in interstate commerce, (3) a foreign trademark application for the same mark and the same goods or services, (4) a foreign registration for the same mark and the same goods or services, and/or (5) extension of an international registration for the same mark and the same goods or services.  By far the most common filing bases are the first two.

In the United States, trademark rights flow from, and are contingent upon, use of the mark.  Although an applicant can keep a U.S. trademark application pending for about two and a half years based only on the stated intent to use the mark, the U.S. Patent and Trademark Office (USPTO) will not register a trademark in a use-based or intent-to-use application absent proof of use in interstate commerce and there is no enforceable trademark right, even at common law, without use of the mark.

More particularly, to obtain a registration of a use-based or an intent-to-use application, the applicant must prove use of the mark for the goods and/or services listed in the application by submitting a specimen showing such use.

If based on a foreign trademark application or registration or an international registration, however, the applicant does not need to use the mark in the United States to obtain a U.S. registration.  The USPTO will register the trademark upon proof that the applicant obtained a foreign registration.

Interestingly, the United States is one of only a handful of countries that require use to register a trademark and have an enforceable right in the mark.  Most countries do not require use of the mark to obtain a registration.

So filing a U.S. trademark application based on a foreign or international registration gets around the use requirement (in the United States and potentially anywhere in the world), at least or the purpose of obtaining a U.S. trademark registration.

But that’s not the end of the story.  The owner of a U.S. trademark registration registered solely on the basis of a foreign or international registration (i.e., without use in the United States) cannot enforce its trademark in a U.S. court.  While some U.S. courts have held that such registrants have standing to sue, even in those courts, the registration would be canceled without use in interstate commerce.

So while a foreign trademark registration can get you a U.S. registration without use in the United States, you probably can’t stop other U.S. users of the mark because your registration would be unenforceable and would not stand up in court.

Now back to GM’s BOLT applications.  This is where it gets interesting.  The applications are not based on use of the marks in the United States or an intent to use in the United States.  Rather, each application is based on a foreign application filing, specifically Brazilian trademark application number 907703178 for CHEVROLET BOLT and 907703070 for BOLT.

Brazil is one of those countries that does not require use to obtain a trademark registration.  So GM could get itself U.S. trademark registrations, albeit unenforceable ones, for BOLT and CHEVROLET BOLT without ever using this exciting new brand anywhere in the world.

Even though GM’s U.S. registrations may be unenforceable “paper” registrations, Gas 2.0′s point still has some merit.  Ownership of U.S. trademark registrations for the BOLT marks could still scare off potential users and keep competitors at bay for a while.

Don’t be surprised, though, to not see a shiny new Chevy Bolt speeding by you on the highway. 

Guest Post: Pace of Wind Innovation Slows, But is Set to Skyrocket Again

September 17th, 2014 by Philip Totaro* No comments »

Totaro & Associates, a Houston, TX based research and consulting firm has released a new research report on the pace of wind turbine technology innovation and proliferation.

IP ownership rankings show General Electric still leading with over 1,400 patent families, and the ability to now leverage the Alstom wind portfolio, which puts the combined total above 1,550.  Siemens has overtaken Vestas for #2 as predicted in last year’s report, and Mitsubishi drops from #4 to #5.

Previously outside the top 10, Guodian United Power has rocketed up into the #4 spot due to more patent filings in 2012 than any other company, although most filings were exclusive to China.

The top 10 wind turbine manufacturers control more than 56% of all wind patent filings, as well as over 77% of the patents which are broadly applicable to the entire industry or potentially infringed.  This strongly suggests the concentration of innovation in wind lies with those who can afford it.

The pace of patent filings has finally dropped for the first time after an average CAGR of 47% during the 2007 – 2011 time-frame.  The report indicates only a 7% growth in the number of global patent filings in wind in 2012 vs. 2011 and a slight decline for 2013 is expected as the recent market downturn has put a damper on research and development (R&D) spending and expenditure on IP protection.

Market conditions indicate that the pace is set to increase again in the coming years due to an increased commitment of expenditure on R&D.  Some companies are spending up to 6% of their revenue on R&D, which is almost double the spend rate in 2010 after the financial crisis.  Filings are expected to return to the levels seen in 2011 by 2015/16, although the average CAGR is expected to be a more modest 5 – 10%.

The research also shows that the US has the greatest number of patent filings on wind turbine technology, and companies have collectively spent over $162M on IP protection with over 8,365 individual patent filings there.  Europe is second at $138M with over 6,100 filings and China third at $61M with over 5,000 filings.  China is poised to overtake Europe for #2 within the next 12 months.

Globally, the entire wind industry has spent $522M to date on patent protection.  Expenditure on IP protection by wind companies is expected to escalate, with $1B to be spent by 2019 and $2B by 2026.

The past year has seen the penetration of some non-practicing entities (NPEs), more commonly referred to as ‘patent trolls,’ into the wind market.  These companies acquire orphaned intellectual property assets or develop their own patent portfolios specifically for the purpose of monetizing against the entrenched players in the industry.

With so many patents available for acquisition in the past 18 months, it is no surprise that these NPEs are seeing an opportunity to take advantage of market timing and attempt to drive up costs for operating companies in wind.

Clean Tech in Court: Green Patent Complaint Update

September 11th, 2014 by Eric Lane No comments »

As with many things, July and August were slow months for green patent litigation.  However, a handful of green patent complaints were filed in the last two months in the areas of solar power, green chemicals, smart meters, and, of course, LEDs.

 

Solar Power

Conlin v. Solarcraft, Inc.

Kevin L. Conlin sued Solarcraft on July 2, 2014 in federal court in Houston, Texas.  The complaint alleges that several patents relating to portable solar power units are invalid or unenforceable due to inequitable conduct.  Conlin further alleges that he should have been named as an inventor on the patents.

Tesla Resolves Chinese Trademark Dispute (Again, This Time With Cash)

August 14th, 2014 by Eric Lane No comments »

Previous posts (here, here, and here) discussed Tesla’s trademark troubles in China.

As it sought to expand into the Chinese market, the electric car maker encountered a businessman named Zhan Baosheng who owned registrations for the TESLA (or “Te Si La” transliterated) trademark in China in both English and Chinese.

While Zhan’s trademark rights initially blocked Tesla from using the mark there, in early 2014 the company announced that it had resolved the matter though a court decision granting it the right to use the TESLA mark in China.

So Tesla seemed to be in the clear until Mr. Zhan, apparently unsatisfied, decided to sue Tesla for trademark infringement.  He seemed to be in it for the money:  the lawsuit demanded that Tesla stop all sales and marketing activities in China, shut down showrooms and charging facilities, and pay him 23.9 million yuan ($3.85 million) in compensation.

It appears that Zhan finally got his pay day.  Tesla recently said it resolved the dispute – this time via a direct settlement with Zhan rather than relying on the Chinese court system.  The Bloomberg report says a Tesla spokeswoman “declined to discuss financial terms” relating to the deal.

Zhan agreed to settle the dispute “completely and amicably” including consenting to cancellation of his Tesla trademark registrations and applications.   He will also transfer his domain names, including tesla.cn and teslamotors.cn to Tesla.

This is not the first time a U.S. clean tech company has faced IP difficulties in China – American Superconductor has been involved in major copyright and trade secret litigation with Chinese wind turbine maker Sinovel.  Also, Apple and Burberry Group had difficulties with securing their trademark rights in China.

It would be interesting to know why Tesla’s initial Chinese court victory was inadequate and left the door open for Zhan’s subsequent lawsuit.  One clear and timeless lesson we can draw from Tesla’s Chinese trademark troubles is that in China, as in legal and business disputes everywhere, money talks.

From Burgers to Biofuels: Trademark Board Rules McDonald’s “Mc” Rights Extend to Biodiesel

August 7th, 2014 by Eric Lane No comments »

In March of 2009 Joel Joseph filed a U.S. trademark application for the mark BioMcDiesel for use in connection with marketing and selling biodiesel fuel.

Needless to say, the owner of the ubiquitous global McBrand was not pleased.  McDonald’s Corporation filed an opposition proceeding before the the U.S. Patent and Trademark Office Trademark Trial and Appeal Board (Board) requesting that the application be denied registration.

In a recent decision, the Board ruled for McDonald’s and held that the application would be refused registration.

As usual, the Board’s focus was on the likelihood of confusion inquiry, specifically here whether Joseph’s use of the BioMcDiesel mark would cause consumer confusion with the McDonald’s family of “MC” formative marks.

Although McDonald’s has been criticized over the years for trademark bullying and overextending the reach of its brand (e.g., the McSleep case), its argument here was a credible one.

The first likelihood of confusion factor was easy:  fame of the McDonald’s marks (a no-brainer).  However, the key factor that drove the Board’s decision was the similarity of the goods/services.

It turns out that McDonald’s is one of the largest suppliers of “yellow grease,” the industry term for fryer grease, for biodiesel production.  The evidence of record included multiple news articles about its biodiesel program, including one entitled “McDonald’s McDiesel”  Go Green Hawaii.”  McDonald’s also promotes its sustainability programs, including its recycling efforts, which have received considerable media attention.

The Board also noted that McDonald’s has been sharing locations with gas service stations since 1993, biodiesel fuel is sold at some of these restaurant and gas station locations, and McDonald’s uses biodiesel to run its delivery trucks (see picture above).

Thus, the Board concluded that consumers would likely be confused by Joseph’s use of the BioMcDiesel mark for biodiesel fuel:

[The evidence of record] is sufficient to show that there is a relationship between gas stations and food service/restaurants, and particularly between Opposer’s restaurants, the food items served in those restaurants, and its yellow grease, and fuel, such that relevant consumers, when confronted with the use of Applicant’s BioMcDiesel mark for biodiesel fuel, would be likely to believe there is an association as to source between that biodiesel fuel and Opposer’s restaurant services and related food products.

As to the similarity of the mark to the McDonald’s family of marks, the Board was not persuaded by Joseph’s arguments that the location of the “Mc” component in the middle of the mark and the fact that biodiesel is not a food product were sufficient to distinguish it.

The Board noted that the McDonald’s family is not limited to marks in which the “Mc” formative is at the beginning of the mark, citing CHICKEN MCNUGGETS, EGG MCMUFFIN, and SAUSAGE MCMUFFIN.  Also, because the McDonald’s marks are so famous, “when third parties use the “Mc” formative, it engenders a similar commercial impression.”

You should think twice before pouring your resources into those McSolar and McWind brands!

More Green Patent PR: Phytonix, Proterro and Others Tout Patents and Licenses

August 4th, 2014 by Eric Lane No comments »

I’ve written before (e.g., here and here) about tech firms’ penchant for patent PR.  Here are several recent contributions to the genre.

 

Phytonix Corporation, based in North Carolina, touts its new U.S. patent for biobutanol production technology in this press release.  The patent is U.S. Patent No. 8,735,651, entitled “Designer organisms for photobiological butanol production from carbon dioxide and water” (’651 Patent).

The ’651 Patent is directed to a biosafety-guarded photobiological butanol production technology based on designer transgenic plants, designer algae, designer blue-green algae (cyanobacteria and oxychlorobacteria), or designer plant cells.

But the company’s IP portfolio doesn’t end here; Phytonix wants you to know that it also has IP relating to its biosafety guarded technology that “uses redundant mechanisms to prevent the proliferation of our organisms outside of a chemicals & biofuels productions environment.”

Query whether Phytonix directly competes with  biobutanol industry leaders Butamax and Gevo, who have been embroiled in contentious patent litigation.

 

Meanwhile, Ion Power Group (IPG) has been busy patenting not only in the U.S. but also in Canada, China, Japan and Russia.  The energy R&D company’s IP law firm announced that IPG’s “ground-breaking” ion power plant technology is the subject of “international patents.”

The press release does not contain the patent numbers, but specific patent info can be found on the company’s patents page.

 

New Jersey-based Proterro recently announced the grant of U.S. Patent No. 8,728,783, succinctly titled “Photobioreactor” (’783 Patent).

The ’783 Patent is directed to a photobioreactor for cultivating photosynthetic microorganisms comprising a non-gelatinous, solid cultivation support suitable for providing nutrients and moisture to photosynthetic microorganisms and a physical barrier covering at least a portion of the surface of the cultivation support.

The news was picked up by Biofuels Digest.  The press release also mentions a new Mexican patent and a prior U.S. patent covering the company’s sucrose-producing cyanobacteria.

 

Of course, not all green patent PR pertains to patent grants.  Some relates to tech transfer.  In this vein, Innovative Environmental Technologies (IET) recently announces an exclusive licensing agreement with Provectus Environmental Products.

IET said the deal involves seven patents, including U.S. Patent No. 7,828,974, with the positively prolix title “The induction of reducing conditions and stimulating anaerobic process through the addition of dried micro-blue green algae and seaweed to accomplish accelerated dechlorinization of soil and groundwater contaminated with chlorinated solvents and heavy metals” and U.S. Patent No. 8,147,694, entitled “Method for the treatment of ground water and soils using mixtures of seaweed and kelp.”

The press release can be found here.

By the way, this breakdown of green patent PR subject matter – the majority being directed to patent prosecution events – is consistent with my findings on patent PR in the clean tech industry discussed here.
