Knauf, Fletcher return to court over long-running Batts dispute
By Suze Metherell
Sept. 29 (BusinessDesk) - Knauf, the German building materials firm, and Fletcher Building, New Zealand's dominant
building supplies company, have returned to court for a cross appeal, the latest instalment of their long-running
dispute over the use of the word "batts" to describe insulation.
Appearing in the Court of Appeal before Justices Tony Randerson, Christine French and Mark Cooper, the legal counsel for
Fletcher's Tasman Insulation subsidiary, Julian Miles QC returned to the argument that Knauf's use of "batt" or "batts"
on the packaging of insulation infringed the "Batts" trademark it has held since 1973.
The two building supplies companies are both appealing aspects of Justice Brendan Brown's May 2014 judgment, which
refused a request from Knauf to revoke the trademark. In the same judgment, Justice Brown also limited Fletcher’s claim
of infringement of the trademark to the use of “batt” in the HTML code on the www.earthwool.co.nz website, which sold
Knauf insulation, and said the use of the word in the installation instructions on the packaging didn’t infringe
Dwarfed by 11-plus boxes of files and three large rolls of Knauf insulation, Miles said the rival company first started
importing its insulation into New Zealand in December 2010, originally in clear packaging labelled "loft roll". However,
during 2011 Knauf began to bring in "what we understand was the same product with different packaging" which included
instructions which referred to the product as "batts". Miles pointed our the difference using the three insulation rolls
in the court room.
Miles argued that Knauf's use of "batts" on its packaging was a "deliberate" attempt to use Fletcher's trademarked term.
He said the change from the original non-offending packaging to the inclusion of the term came after market research
showed the widespread use of the term over the past four decades.
Knauf "knew (Batts) had a trademark, the only inference that you can draw from that is that they intended to undermine a
trademark," he said. It was irrelevant how the term was used in other countries, as this dispute concerned only the New
Knauf, represented by Clive Elliott QC, is appealing Justice Brown’s ruling that the "Batts" trademarked term for
insulation is not generic.
The hearing is set down for three days in the Court of Appeal, and is continuing.
