PHIUS Tries to Trademark ‘Certified Passive House Consultant’

Also used by the Passivhaus Institut in Germany, the phrase is now being claimed as a trademark by a rival U.S. organization

UPDATED on 3/29/2012

On January 12, 2012, the Passive House Institute U.S. (PHIUS) filed a trademark application for the letters “CPHC,” which stand for “certified passive house consultant.”

The phrase and abbreviation are also used by the Passivhaus Institut in Darmstadt, Germany. In spite of that fact, PHIUS is taking legal steps to prevent any European-affiliated Passivhaus group, including the Passive House Academy of Ireland, from using the initials “CPHC.”

In August 2011, the Passivhaus Institut in Germany severed its relationship with PHIUS. It’s now up to the U.S. Trademark Office to determine whether the disowned U.S. offspring of Dr. Feist’s institute can seize control of a phrase used by Passivhaus groups around the world.

As GBA reported previously, PHIUS sent out an e-mail to many American architects on January 17, 2012, warning recipients that only PHIUS was allowed to use the phrase “certified passive house consultant.”

For more information on the issue of trademarking phrases used by Passivhaus designers and builders, see Can ‘Passive House’ Be Trademarked?

Reacting to the news of PHIUS’s attempts to squelch unauthorized utterances of “CPHC,” Gregory Duncan, an architect working in Brooklyn, New York, composed the following tweet: “I wonder if PHIUS will send a cease-and-desist letter to the Canadian Prostate Health Council as well?”

PHIUS sends a threatening letter to New York Passive House

GBA has just learned that on January 18, 2012, PHIUS sent a letter to New York Passive House, a regional Passivhaus organization. The letter stated, “It has come to our attention that New York Passive House has been using PHIUS’s e-mail list to solicit business on behalf of Passive House Academy. … We do not know how you acquired this list, but the e-mail list is one of PHIUS’s trade secrets. PHIUS did not authorize you or any other organization to use this list. We demand that you immediately stop using this list. … If you do not comply with the demands set forth in this letter, we must conclude that you intend to use the confusion created by your trademark infringement to attempt to divert business rather than seeking to develop Passive House Academy’s business legitimately.” (To read the entire letter, click on the image below.)

Responding to the cease-and-desist letter, three members of the New York Passive House board (Andreas Benzing, Floris Keverling Buisman, and Ken Levenson) explained, “NYPH has never obtained a PHIUS email list and never used a PHIUS email list – the accusation is fanciful. … NYPH has built its own list.”

Needless to say, these demands and cease-and-desist letters are keeping several lawyers busy.

New York Passive House responds to PHIUS

On January 26, 2012, a lawyer hired by New York Passive House responded to PHIUS’s letter. An announcement from the board was sent to New York Passive House members:

“Dear NYPH Member,

“Earlier this week NYPH received a cease and desist letter from PHIUS attorneys (see here). Yesterday, a letter from Frank Taddeo Jr., the attorney retained by NYPH, was sent back in response (see here). Essentially, the letter has four points/objectives:

“1. Clarify the current status of the alleged trademarks: there are no trademarks existing, contrary to PHIUS assertions.

“2. State unequivocally that NYPH has never used a PHIUS email list and that the accusation is baseless.

“3. To be clear that NYPH is no way in competition with PHIUS nor an agent of any entity in competition with PHIUS.

“4. Given the above three points, any further action against NYPH by PHIUS will be frivolous.

“With this most unpleasant exchange behind us, the NYPH board and membership will redouble our efforts toward building a strong and transparent Passive House community, based on a shared interest in building science, Passive House building specifically, and open knowledge sharing for the benefit of all.

Sincerely,

NYPH Board:

Andreas Benzing

Floris Keverling Buisman

Ken Levenson”

The Passive House Academy ignores PHIUS’s cease-and-desist request

Ignoring PHIUS’s threats, the Passive House Academy was still using the term “certified passive house consultant” in its advertising in late March 2012.

    Professional designation CPHC
    As the matter of fact, Martin, the PHIUS Certified Passive House Consultant training was the first ever English language course on Passive House design principles not only in the US but world wide. It was launched in May 2008. At that time the course in Germany had the designation "Passivhaus Planer" and existed only in the German language (if you look you can still find some testimony of that earlier name in their web address still used today: http://www.passivhausplaner.eu/englisch/index_e.html)

    The CEPH - Certified European Passive House course (currently being offered by the competition as international and falsely advertised as the equivalent to the PHIUS CPHC program) was a Certification in the English language program called "European Passive House Planner". It was unveiled to the public for the first time during the 2009 International Passive House conference in Frankfurt Germany by Annette Baehr, a PHI staff member. The proceedings of this conference are a nice record of this and available from the PHI. They show clearly the title of her presentation for anyone who likes to read up on it to verify the facts: Certification as a European Passive House Planner.

    PHIUS pioneered its own Certified Passive House Consultant, CPHC course a full year ahead of this launch independently in the US.

    In attempts to clean up the awkward initial English translation, the PHI later looked over the big pond and renamed, one must argue after PHIUS' course, its training "Certified Passive House Designer and Consultant".
