Trademark dispute: HITACHI vs hitasi

On October 16, 2023, the Japan Patent Office (JPO)dismissed an opposition claimed by Hitachi, Ltd. against TM Reg no. 6621366 for wordmark “hitasi” by finding dissimilarity to and unlikelihood of confusion with “Hitachi”.

[Opposition case no. 2022-900496]

Opposed mark

A Chinese individual filed a wordmark “hitasi” for use on glass, unworked or semi-worked, except building glass; mangers for animals; drinking troughs; toothbrushes, electric; nail brushes; comb cases; make-up brushes; gardening gloves; glass vials; decanters; vacuum bottles [insulated flasks]; oven mitts; place mats, not of paper or textile; drinking straws; bird baths; tanks [indoor aquaria]; utensils for household purposes in class 21 with the JPO on April 5, 2023.

The JPO granted protection of the opposed mark on September 29, 2022 and published it for a post-grant opposition on October 7, 2022.


Opposition by HITACHI

Hitachi, Ltd., founded in 1910, highly diversified Japanese manufacturing corporation that comprises more than 1,000 subsidiaries, including 335 overseas corporations filed an opposition on November 29, 2022 with the JPO and claimed the opposed mark shall be cancelled in contravention of Article 4(1)(xi) and (xv) of the Trademark Law due to similarity to and likelihood of confusion with its famous house mark “Hitachi”.

To bolster their arguments, Hitachi cited the IP High Court ruling dated Jan 27, 2022 that admitted a likelihood of confusion between “HITACHI” and “hihachi” when used on air conditioners for industrial purposes; non-electric cooking heaters for household purposes; non-electric stoves for household purposes in class 11.


JPO decision

The JPO Opposition Board found a high degree of reputation and popularity of the cited mark “HITACHI” as a source indicator of the Hitachi Group and their business.

However, the JPO pointed out a low degree of similarity between the marks by stating that:

  1. From appearance, there is a difference in the letter “s” and “CH”. It would cause non-negligible effect on the overall visual impression of the marks which consist of relatively few letters (sir or seven characters). In this respect, two marks are unlikely to cause confusion visually.
  2. Aurally, there is a difference in the last sound of “si” and “chi”. It would cause non-negligible effect on the overall sound of the marks which consist of three syllables. The Board has a reason to believe that two marks are unlikely to cause confusion phonetically.
  3. From concept, both marks are unable to compare since the opposed mark does not have any specific meaning, whereas the cited mark gives rise to a meaning of “HITACHI” as a source indicator of the claimant.

Given a low degree of similarity of the marks, the Board said, it is unlikely that relevant consumers confuse the source of the goods in question bearing the opposed mark with Hitachi, Ltd. or other entity systematically or economically connected with the claimant even if the cited mark “HITACHI” has been famous trademark

Based on the foregoing, the Board dismissed the entire allegations by Hitachi and decided validity of the opposed mark as the status quo.

Japan IP High Court Refuses Trademark Protection for Orange Color Mark

On 23 June 2020, the Japan IP High Court decided a case concerning a single color mark that was rejected for registration by the Appeal Board of the Japan Patent Office (“JPO”).

Single Color Mark

On 1 April 2015, Hitachi Construction Machinery (“Hitachi”) filed an application for trademark registration with JPO consisting of a single color per se, namely orange (Munsell: 0.5YR5.6/11.2) over the goods of hydraulic excavators, wheel loaders, road loaders, loaders [earch moving machines] in class 7, and rigid dump trucks in class 12 (TM Application no. 2015-29999).

TM Application No. 2015-29999

By the decision of 19 September 2019, the Appeal Board of JPO declared the applied color mark to be refused in contravention of Article 3(1)(iii) and Article 3(2) of the Trademark Law, finding that the graphic representation of the color mark constituted the “mere single orange color, without contours”. If so, the mark is not inherently distinctive and it is lacking acquired distinctiveness. In the course of the appeal trial, Hitachi amended and restricted the designated goods to “hydraulic excavators”.

Article 3(2) is a provision to allow registration of any mark with which the relevant public will associate a particular source, manufacturer, or producer over time through the trademark owner’s usage.

On 30 October 2019, Hitachi appealed against the JPO decision.

IP High Court decision

At the outset, the court stated it is inevitable on the case concerning single color mark to take the interest of competitors who deal with the goods in question into consideration since allowing one trader to exclusively use this color would likely to cause unjust competitive practice in form of monopolistic power of use in favor of one trader only.

From the produced evidence, Hitachi has allegedly used the color in question on hydraulic excavators and other construction machines since 1974.

Hitachi Hydraulic Excavators

Hitachi consecutively holds a 20% market share (14.6%) of hydraulic excavators over the past four decades in Japan. The research showed that approx. 95.9 % (185 out of 193) of traders in the construction industry were able to associate the color with Hitachi.

In the meantime, several competitors use similar color on hydraulic excavators

In the decision, the court found orange color is one of the colors commonly seen in our daily life. Besides, the Japan Industrial Standard (JIS) adopts orange as a safety sign-color aiming to prevent harm to the human body and damage to properties. Because of it, at construction sites, we often see several items colored in orange, e.g. helmets, rain suits, guard fens, work clothes, tower cranes, construction vehicles.

Hitachi Hydraulic Excavators have other colors, in fact, namely, a house mark “HITACHI” colored in white, buckets (attachments), cockpits, and crawlers colored in black. If so, the applied mark shall be capable of playing the role of source indicator in combination with these. Thus, the court would not find reasonable grounds to believe that the orange color per se acquired distinctiveness as a source indicator of Hitachi’s Hydraulic Excavators.

The court even suspected credibility of the research by finding that it narrowly targeted traders or consumers who own more than 10 hydraulic excavators, precisely it showed 36.8% in light of initial research number of targets, 502 persons, and the questionnaire ‘Please answer. What maker do you think hydraulic excavator is?” was insufficient to conclude acquired distinctiveness since its answer may simply suggest one of the colors of Hitachi’s Hydraulic Excavators.

Even if hydraulic excavators market in Japan is an oligopoly with five makers accounting for 90 % of the industry share, and the orange color has been consecutively used by Hitachi only, it does not mean every competitor agreed to refrain from using the color given orange has been used on various goods in the construction and agriculture industry in general.

Based on the foregoing, the court affirmed the JPO decision and dismissed Hitachi’s allegations in contravention of Article 3(1)(iii) and 3(2).

Thus, it is obvious that a very high standard of distinctiveness needs to be attached to a single-color mark if the same has to be claimed for trademark protection.

This case was a second court decision concerning a single color mark.
The first case, Reiwa1(Gyo-ke)10119 ruled on March 11, 2020, also ended with the rejection of a single orange color mark in contravention of other ground, Article 3(1)(vi).

How JPO Examines Color Marks

As of now (12 July 2020), 543 color marks were applied for registration with JPO since the commencement of the Non-Traditional trademark application in April 2015.
So far, only 8 marks are successfully registered. See below.

In sum, the registration rate of color mark is barely 1.5%!
It is noteworthy none of a ‘single’ color mark has been granted to registration.
