Vinson Conlan’s LED Patent Report: What’s at Stake in Cree v. Feit?

July 7th, 2015

A previous post reported on the LED patent lawsuit between North Carolina LED manufacturer Cree and Feit Electric Company in which Cree has alleged infringement of a number of utility and design patents.

There are several patents involved with this case but none as far reaching as U.S. Patent No. 8,596,819 (’819 Patent). Let’s look at the first claim:

1.  A lighting device comprising at least one light emitting diode, said lighting device, when supplied with electricity of a first wattage, emitting output light with a wall plug efficiency of at least 60 lumens per watt of said electricity.

This claim covers all LED devices with an efficacy over 60 lumens per watt with at least one LED.

The latest Energy Star luminaire requirements (taking effect in 2016) for all luminaire categories, but track need to meet or exceed 60 LPW. Most large retailers have relied upon Energy Star to help qualify products for sale to residential customers. In some cases, products without Energy Star will not be considered for sale in retail outlets.

Energy Star is required to qualify for many utility rebate programs. Energy Star is a Department of Energy program and has been made aware of the ’819 Patent. They were made aware of this patent issue before the latest luminaire requirements were finalized.

Those who honor the ’819 Patent would be denied rebate dollars and the potential to sell into some large volume accounts because meeting Energy Star requirements would force them to infringe the patent.

Energy Star has the best interest of the country in mind, but one has to question their decisions when their policies will clearly steer rebates dollars and retail business directly towards a single patent holder.

This case is about more than one company against another, it is the test of a patent that could be used successfully to deny businesses the opportunity to get an Energy Star listing and qualify for rebate dollars.

For those looking to sell into the commercial channel and get added to the Design Lights Consortium (DLC) qualified product list, they will only qualify for display case lighting and directional interior categories. All lamps would infringe as well. Like Energy Star, DLC qualified products are eligible for rebates.

Another Cree patent in this lawsuit is U.S. Patent No. 8,628,214 (’214 Patent).  This patent is very similar to the ’819 Patent. The first claim of the ’214 Patent reads:

 1.  A lighting device comprising:a first string of solid state light emitters in series, the first string comprising at least two solid state light emitters,

a second string of solid state light emitters in series, the second string comprising at least two solid state light emitters,

a third string of solid state light emitters in series, the third string comprising at least two solid state light emitters,

the lighting device, when supplied with electricity of a first wattage, emitting output light with a wall plug efficiency of at least 60 lumens per watt of the electricity.”

Perhaps it is time for those who support Energy Star and DLC to consider a revised set of efficacy standards that promote free trade and offer their customers a wider range of options. The following organizations have influence, and as objective third parties can help all interested parties find solutions that will help save energy without infringing these patents.

Ford EV Patents Open, Not Free; You Can License For a Fee

June 16th, 2015

Once is an isolated incident, twice could be a coincidence, but three times – that may make a trend.  Following Tesla’s big patent giveaway about a year ago and Toyota’s fuel cell vehicle patent limited license offer a few months ago, Ford recently announced that it has “opened” its electric vehicle patent portfolio.

Don’t get too excited, though.  This one is fundamentally different from the prior patent pledges.  Ford is not donating its patents or even offering limited-time royalty-free licenses to the patents.

Rather, Ford is offering the patents for license “for a fee” as the company’s press release explains.  In view of the other automakers’ EV freebies, Ford issued a brief statement in defense of it’s for-profit licensing scheme (reproduced here from a Financial Times article):

Defending the decision to charge for the patents, the company said “We’re proud of the work that we do.”  It added: “From the research we’ve conducted already, we feel that licensing is appropriate.”

Not that there’s anything wrong with that.  To the contrary, companies should generate revenue from their R&D, their innovation, and their patents.

But the headline of the announcement obscures the fact that it’s a for-profit licensing venture (“Ford Opens Portfolio of Patented Technologies to Competitors to Accelerate Industry-Wide Electrified Vehicle Development”).

In intellectual property, the word “open” signals free use or public domain (e.g., open source), and the headline is particularly misleading in view of the recent Tesla and Toyota royalty-free patent license moves in this field.  Note Toyota’s press release also used “open” (“Toyota Opens the Door and Invites the Industry to the Hydrogen Future”).

Of course, reasonable people can differ in opinion as to whether the developing EV industry is better served by truly open patent portfolios or revenue generating licensing opportunities.  But either way, the patent holders should not mislead and should get the messaging right.

By the way, this trend of pledging patents appears to be a hot topic:  it’s the subject of a recent article by Professor Jorge Contreras called Patent Pledges and a conference held just yesterday at American University.

 

Guest Post: Vinson Conlan’s LED Patent Update

June 2nd, 2015

Lighting Science Group expanded their intellectual property for their LED Disc Light (Glimpse) with three recent patents.

The trio of patents cover LED light fixtures that are low profile and designed to cover recessed light fixtures and junction boxes. Most of these fixtures look like recessed trims with a lamp or a recessed light fixture trim with a lens.

Their latest patent is written to cover fixtures that are designed to cover a recessed light fixture housing and a junction box with a driver located between the light fixture and the junction box or recessed housing. The ratio of height to diameter is not included in the first claim as it was on the original patent, U.S. Patent No. 8,201,968 (’968 Patent).

The combination of patents covers many fixture types currently manufactured in North America. Examples of their products can be found here.

The second patent, U.S. Patent No. 8,672,518, entitled “Low profile light and accessory kit for the same”, issued March 18, 2014.

U.S. Patent No. 8,967,844, entitled “Low profile light and accessory kit for the same” (’844 Patent), issued on March 3, 2015. This is the third of the patents issued that provides coverage for their disc light LED product.

All of the patents claim the benefit of U.S. Provisional Application Ser. No. 61/248,665, filed Oct. 5, 2009.

The following description from the ’968 Patent has been separated into two claims in the ’844 Patent:

wherein the heat spreader, the heat sink and the outer optic, in combination, have an overall height H and an overall outside dimension D such that the ratio of H/D is equal to or less than 0.25; wherein the combination defined by the heat spreader, the heat sink and the outer optic, is so dimensioned as to: cover an opening defined by a nominally sized four-inch can light fixture; and, cover an opening defined by a nominally sized four-inch electrical junction box.

In place of the above, claim 1 in the ’844 Patent adds the following:

…and a power conditioner disposed and configured to receive AC voltage from an electrical supply and to provide DC voltage for the plurality of LEDs; wherein the power conditioner is disposed, configured and sized to fit at least partially within an interior space of: a nominally sized can light fixture; and, a nominally sized electrical junction box.

 

Another recent patent of interest

Copper Technologies (see Halo brand products) was granted U.S. Patent No. 9,010,956,entitled “LED module with on-board reflector-baffle-trim ring” (’956 Patent). Claim 1 reads as follows:

A light module, comprising:

a heat sink comprising an internal surface surrounding a heat sink cavity formed therein, the internal surface comprising:

a mounting region; and

a reflector region extending from the perimeter of the mounting region to a distal end;

one or more light sources coupled to the mounting region within the heat sink cavity; and

a plurality of mounting pads disposed circumferentially around a portion of the heat sink to separably couple the light module to a housing having a five inch diameter cavity or a housing having a six inch diameter cavity, each mounting pad comprising:

a first receiving hole; and

a second receiving hole,

wherein either the first receiving hole or the second receiving hole is coupled to a torsion spring,

wherein when the torsion spring is coupled to the first receiving hole, the light module is coupled to the housing having the five inch diameter cavity, and

wherein when the torsion spring is coupled to the second receiving hole, the light module is coupled to the housing having the six inch diameter cavity.

One of the embodiments, which is on the shelf at a popular retail DIY chain, can be seen here.

The ’956 Patent protects their current low cost LED trim; many low cost trims use a similar construction.

Jury Verdict for Everlight Knocks Out Nichia Patents

May 13th, 2015

 

A previous post discussed the declaratory judgment complaint (Everlight-Nichia ComplaintEverlight Electronics filed against Nichia in federal court in Michigan in April 2012.

Everlight sought declaratory judgment of non-infringement, invalidity, and unenforceability due to inequitable conduct of two patents owned by Nichia:  U.S. Patent Nos. 5,998,925 entitled “Light Emitting Device Having a Nitride Compound Semiconductor and Phosphor Containing Garnet Fluorescent Material” (’925 Patent), and 7,531,960 entitled “Light Emitting Device with Blue Light LED and Phosphor Components” (’960 Patent).

Everlight suffered a setback later that year when the court granted Nichia’s motion to dismiss the inequitable conduct claims.

However, the Taiwanese company scored a big victory recently when the Michigan jury unanimously found multiple claims of the ’925 and ’960 Patents invalid.  More particularly, claims 2, 3 and 5 of the ’925 Patent were found to be invalid due to obviousness, claims 2, 14 and 19 of the ’960 Patent were found to be invalid due to obviousness, and claims 14 and 19 of the ’960 Patent were also found invalid for lack of enablement.

The jury declined to find claims 2, 3 or 5 of the ’925 Patent to be invalid on the additional enablement ground.

While this is an important win for Everlight, it is just one battle in a sprawling patent war between these two LED rivals.  The litigation dates back to 2005 when Nichia first targeted Everlight for patent infringement and extends to various venues around the world.

Nichia has sued an Everlight customer in a Tokyo District Court asserting the Japanese counterpart to the ’960 Patent (Japanese Patent No. 4350094).  Nichia also filed suit against Everlight in Germany asserting the European counterpart to the ’925 Patent (European Patent No. EP 0 936 682).

In addition to this DJ action, Everlight has filed a number of reexaminations proceedings targeting Nichia’s LED patents.

CEPGI Year in Review Shows Green Patents Hit All-time High in 2014

May 6th, 2015

The Clean Energy Patent Growth Index (CEPGI) recently released its 2014 Year in Review.  Researched and published by the Heslin Rothenberg law firm, CEPGI is a quarterly report on clean energy patents issued in the United States.

The big news is that the 3609 green patents granted in 2014 is the highest annual total since CEPGI began tracking green patent trends in 2002.  This is a jump of 434 from 2013.

The largest number of green patents was in solar technology, with 1238 solar patents, a 28 percent increase from the previous year.  Fuel cell patents were in second place, with 1024 (a 27% jump from 2013), followed by wind patents (623), and hybrid/electric vehicle patents (521).  Biofuels patents (230) were in the fifth position.

The top green patentee for 2014 was Toyota, which had 149 patents granted, followed by General Motors, with 126 granted green patents, Samsung (102 patents), Hyundai (101 patents), and Honda (97 patents).  The overall leader in granted green patents since 2002 is still General Motors, followed by Honda, Toyota, GE, and Samsung.

By technology sector, Toyota was the fuel cell patent leader in 2014 with 101 fuel cell patents granted, Samsung was the top solar patentee of the year (37 patents), and Hyundai topped the list for hybrid/electric vehicle patents, with 56.  While GE had been the top wind patentee for eight years running, Vestas came out on top in 2014, with 80 granted wind patents.

In 2014, green patent owners were a diverse group:  according to the report, “over 1500 entities contributed to the record total of Clean Energy patents last year.”

CEPGI also breaks out its data by jurisdiction, looking at the countries and individual U.S. states of green patentees.  The United States was the 2014 leader with 1504 green patents granted.  Japan took second place, with 696 patents, followed by Korea (346), Germany (316), Denmark (120), and Taiwan (118).

California was the leading U.S. state, with 385 patents, followed by Michigan (227), New York (132), and Texas (77), Ohio (56), and Massachusetts (55).

CleanTech PatentEdge Annual Report Shows Green Patenting Grew in 2014

April 21st, 2015

Berkeley-based IP Checkups recently published its 2014 Annual Report on cleantech patenting trends.  Based on the firm’s proprietary green patent database -  Cleantech PatentEdge™ - the report contains much interesting analysis driven by this powerful data analytics tool.

The major finding of the report is that, after a year of decline in 2013, worldwide patent activity grew last year, rising consistently in each quarter of 2014.  This is measured by the number of cleantech patent documents published, which typically means a lag time of 18 months from application filing date.

In the United States, the number of published cleantech patent applications grew by 8% from 2013 to 2014, and the number of U.S. patent publications and grants reached a five-year high.

Looking across all cleantech sectors, the report found that U.S. patent activity increased by an average of 13% in 2014, with renewable energy generation being the leading sector.  Within that sector, solar and biofuels showed the most growth.

The report lists the top twenty worldwide cleantech patent assignees.  Samsung, Toyota, and Panasonic topped the list, with General Electric and Mitsubishi rounding out the top five.

The patent assignees are broken out by industry sector, and the report provides other useful information, such as an in-depth look at patenting trends in transportation and analysis of cleantech venture capital funding trends.  Significantly, cleantech VC funding saw a 28% YOY increase from 2013 to 2014.

BASF Brings Battery Battle to the Border

April 14th, 2015

A previous post reported that chemical giant BASF and UChicago Argonne LLC (Argonne) sued Belgium-based Umicore and Japan-based Makita Corporation for infringement of two patents relating to cathode materials for lithium-ion batteries.  That lawsuit was filed February 20, 2015 in the U.S. District Court for the District of Delaware.

The same day BASF and Argonne filed a complaint in the U.S. International Trade Commisson (ITC) asking the ITC to investigate whether Umicore, Makita and their U.S. subsidiaries have imported and sold in the United States lithium ion cathode materials and batteries that infringe the same patents.

The ITC is a federal agency that investigates trade and importation issues, including conducting quasi-judicial proceedings involving alleged infringement of intellectual property rights by importation of accused products pursuant to 19 U.S.C. § 1337.  It is a popular forum for patentees (though only injunctive relief is available, not monetary damages) because the proceedings progress much faster than those in the federal courts.

The patents-in-suit are U.S. Patent Nos. 6,677,082 (’082 Patent) and 6,680,143 (’143 Patent), both entitled “Lithium metal oxide electrodes for lithium cells and batteries” and directed to a lithium metal oxide positive electrode for a non-aqueous lithium cell.

The cell is prepared in its initial discharged state and has a general formula xLiMO2.(1−x)Li2M′Oin which 0<x<1, and where M is one or more ion with an average trivalent oxidation state and with at least one ion being Mn or Ni, and where M′ is one or more ion with an average tetravalent oxidation state.

According to the ITC complaint, Argonne is the owner of the ’082 and ’143 patents and BASF produces lithium ion cathode materials under an exclusive license to the patents.

Recently, the ITC issued a Notice announcing that it would investigate BASF’s and Argonne’s claims of infringement.

BASF and Argonne have requested a limited exclusion order that would prevent Umicore and Makita from importing Umicore’s cathode materials, allegedly marketed and sold under the Cellcore product group, and certain Makita power tools using lithium ion batteries.

Although Umicore and Makita are now squeezed in both the ITC and federal court, they may ask the court to stay the parallel court action in view of the ITC investigation.

Big Win for Butamax as PTAB Knocks Out All Claims of Gevo Patent

April 6th, 2015

Previous posts (e.g., here and here) discussed various threads of the major biofuels patent litigation between BP-DuPont joint venture Butamax and the advanced biofuels company Gevo.

A relatively new mechanism for challenging the validity of a U.S. patent is inter partes review (IPR), an administrative trial proceeding before the U.S. Patent and Trademark Office’s (USPTO) Patent Trial and Appeal Board (PTAB) in which a third party can challenge the validity of a patent based on printed prior art publications.

Last year Butamax filed a petition with the PTAB for IPR of Gevo’s U.S. Patent No. 8,546,627 (’627 Patent).  The ’627 Patent is entitled “Renewable compositions” and directed to processes for preparing a renewable jet fuel.

The claimed processes comprise fermenting biomass with a microorganism, dehydrating the resulting alcohol to form biofuel precursors, and then subjecting the biofuel precursors to processes such as oligomerization, hydrogenation, and aromatization to form the fuel.

In a recent decision, the PTAB ruled that all 21 claims of the ’627 Patent are invalid in view of several prior art references cited by Butamax.

More particularly, the PTAB held that U.S. Patent Application Publication No. 2008/0132741 to D’Amore discloses five of the seven steps of independent claim 1 of the ’627 Patent.  Because the sixth and seventh steps of claim 1 are recited as optional, D’Amore was found to anticipate the claims.  D’Amore was also held to anticipate dependent claims 7, 11 and 14 of the ’627 Patent.

As the primary prior art reference, the PTAB applied D’Amore in combination with several other printed publications in holding all of the claims invalid.  The PTAB also considered ASTM D1655 jet fuel standards as an important secondary reference and found that D’Amore in combination with the standards rendered claims 2-7, 11, 14 and 18-21 obvious.

The PTAB found an additional ground for invalidity of independent claim 18 in International, or PCT, Patent Publication No. WO 2007/061903 to Bradin.  Bradin is entitled “Alternative fuel and fuel additive compositions” and directed to alternative gasoline, diesel fuel, marine diesel fuel, jet fuel, and flexible fuel compositions including an alcohol and/or a glycerol ether or mixture of glycerol ethers, which can be derived from renewable resources.
