  • Copyrights

    Nature of right

    Works created by an author are protected subject to certain exceptions specified in the Copyright Act, such as private use, citations and school text book use. "Works" means a production in which thoughts or sentiments are creatively expressed and which falls within the literary, academic, artistic or musical domain.

    No fixation to a tangible medium (except for movies) or registration is required.

    The copyright arises and is protected from the moment of creation.

    Copyright owners have the exclusive right to reproduce, publicly perform, screen, transmit, recite, exhibit or distribute, transfer, lend reproductions, translate, adapt the work and use derivative works.

    Moral rights of an author and neighboring rights are recognized under the Copyright Act.

    Legal framework

    The Copyright Act (Act No. 48 of 1970) (the Copyright Act) governs copyrights.

    Japan became signatory to Berne Convention in 1899, to Universal Copyright Convention in 1956, International Convention for the Protection of Performers, Producers of Phonograms and Broadcasting Organizations in 1989, Convention for the Protection of Producers of Phonograms Against Unauthorized Duplication of Their Phonograms in 1978, Agreement on Trade-Related Aspects of Intellectual Property Rights in 1994, World Intellectual Property Organization Copyright Treaty in 2000 and World Intellectual Property Organization Performances and Phonograms Treaty in 2002.

    Duration of right

    Copyright protection lasts for the life of the author plus an additional 70 years. Some special calculations are applicable for copyrightable works made before or during the Second World War.

    For an anonymous work or a pseudonymous work, the copyright lasts for a term of 70 years from its first publication, or a term of 70 years from the death of the author if the author is known, whichever expires first.

    For a work owned by an entity (eg, work made for hire), the copyright lasts for a term of 70 years from the work's first publication. If it is not made public within the 70-year term, the copyright lasts for 70 years after the creation.

    If a work is a movie, its copyright endures for a term of 70 years from its first publication. If the movie is not made public, the copyright lasts for 70 years after the creation of the movie.

    Ownership / licenses

    Exercise of a jointly owned copyright requires consent from the other joint owner(s) of the copyright. However, each joint owner cannot withhold consent without reasonable grounds.

    Exclusive and non-exclusive licenses, as well as transfer of copyright are recognized. Moral rights are not transferrable and not waivable.

    Remedies for infringement

    No registration is required to seek remedies for infringement.

    Monetary damages can be compensated. There are certain statutory presumptions to calculate damages but punitive damages are not available under Japanese law.

    Injunctive relief, including seeking/preventing importation of infringing goods, is available as a remedy.

    For moral rights, measures to correct and restore the honor and reputation of the author or performer are available (eg, publishing an apology in a newspaper).

    Each joint owner can seek a remedy without the other owner's consent.

    Criminal penalties are possible for infringement of copyright.

  • Mask works / topographies

    Nature of right

    The layout-design of semiconductor integrated circuits is protected.

    A semiconductor integrated circuit means a product having transistors or other circuitry elements inseparably formed on the surface of a semiconductor material or an insulating material, or within a semiconductor material and designed to perform electronic circuitry functions.

    Layout-design means a layout of circuitry elements in semiconductor integrated circuits and the lead wires connecting such elements.

    Registration with the Software Information Center is required.

    Owners have the exclusive right to manufacture, transfer, lease, display or import a semiconductor in which mask work is embodied for business.

    An owner cannot assert its right against the same mask work that was independently developed.

    Legal framework

  • Trade secrets

    Nature of right

    Illicit obtainment of trade secrets and use and disclosure of trade secrets for unjustified purposes are regulated under the Unfair Competition Prevention Act (UCPA)(Act No. 47 of 1993).

    The UCPA defines trade secrets under a 3-prong test:

    • Information is "technical or business information useful for business activities such as manufacturing or marketing methods"
    • Information is "managed as a secret" and
    • Information is "not publicly known."

    Legal framework

    The UCPA is the main governing law regarding trade secrets. The UCPA does not require any registration or filing of trade secrets to protect them.

    Duration of right

    There is no specific duration of right or protection period of time under the UCPA. As long as a trade secret falls under a trade secret defined under the UCPA, it will be protected as such by the UCPA.

    Ownership / licenses

    The UCPA is silent on joint ownership of and licensing of trade secrets. As long as these do not undermine trade secrets to meet the 3-prong test, the trade secrets will be still protected.

    Remedies for infringement

    Monetary damages can be levied. There are certain statutory presumptions to calculate damages but punitive damages are not available.

    Injunctive relief is available as a remedy.

    Criminal penalties are available for theft and use of trade secrets.

  • Intellectual property in employment context

    Employees

    The "work for hire" doctrine is applicable to copyrights and mask works. The doctrine is also applicable to patents as long as it is agreed in the work rules or employment agreement that the work for hire patents are inherently owned by the employer in advance. Employees must be reasonably compensated by an employer for the work for hire patents, patent assignments or grant of an exclusive license. The law does not provide the compensation figures but certain factors to be taken into consideration are provided and the amount must be reasonable. For copyrights, a work must be made public under the name of an employer except for computer program related copyrights.

    Even if an employer did not provide that patents created by employees are inherently owned by the employer from the moment of their creation in the work rules or employment agreement, statutes give an employer a right that is similar to a shop right within the scope of a non-exclusive license. This only applies to patents.

    Consultants / contractors

    In practice, consultants and contractors are often required to sign written agreements to assign all intellectual property related to their work for the company. Some courts have applied the concepts mentioned in "Employees" section above to consultants and contractors given the fact that relationship was an employment relationship due to misclassification (ie, disguised service/independent contractor agreement). It is recommended that written contracts expressly assign all intellectual property to the company retaining the consultant/contractor.

  • Key commercial contract considerations

    Registration of commercial agreements

    There is no general registration requirement for commercial contracts. Material contracts of publicly-traded companies may require limited disclosure.

    Patent license or trademark license for statutory exclusivity requires registration to be enforceable. Registration of non-exclusive licenses for trademarks is possible in order to put potential buyers of the trademarks on notice of the license. Such registration is, however, not required.

    Registration of copyright licenses is not available in Japan, although transfer or assignment of copyrights can be registered to assert such assigned rights against third parties.

    Recognized language of commercial agreements

    Japanese language is used for consumer-facing commercial agreements though it is not mandatory for a contract to be enforceable. In business transactions, English agreements are not common but they are enforceable.

    Country-specific issues for online content

    Does not apply for this jurisdiction.

    Enforceability of online/clickwrap/shrinkwrap terms

    Online terms are generally considered enforceable if conspicuous and users have an opportunity to review terms in advance.

    Under the Civil Code, terms of service or use would fall under the definition of the adhesion contract (i.e. template terms and conditions prepared by one party for agreements between unspecified counterparties which is expected to be used without variation). To have an adhesion contract legally binding, consents from counterparties to execute the adhesion contract is necessary. In addition, to amend adhesion contracts, the content of the amendment must be (i) beneficial for the counterparties or (ii) consistent with the original intention of the adhesion contract and its underlying rationale (several factors will be considered in making this determination), or the party shall get consents from counterparties.

    The Electronic Contract Act (Act No. 95 of 2001) allows a consumer who had erroneous operation of a computer (eg, accidental click) to cancel the contract if the company does not take appropriate measures ( eg, easily understandable order confirmation display) for the consumer to reconfirm the details of the order before the final click.

    Governing law

    Choice of governing law and venue for resolution of disputes specified in a contract is generally accepted and recognized by courts in Japan.

    It should be noted that under Japanese conflict law, in consumer contracts, a consumer may require additional application of the law of the consumer's residence in addition to agreed governing law.

  • Key commercial contract terms

    Enforceability of warranty disclaimers

    Warranty disclaimers are generally enforceable unless sellers are aware of a defect in the product(s) at the time of sale.

    For disclaimers against consumers, even if the seller is not aware of a defect in the product(s) at the time of sale, comprehensive disclaimers are not enforceable under the Consumer Contract Act (CCA) (Act No. 61 of 2000).

    Enforceability of exclusions/limitations of liability indemnification

    Exclusions and limitations of liability are usually enforceable unless they are grossly unfair. In consumer contracts, full exclusions or partial exclusions in case of gross negligence or willful misconduct are unenforceable under the CCA.

    Indemnification

    The concept of indemnification does not exist under Japanese law. Instead, a contract party will be entitled to certain remedies upon breach of contract, such as damage claims and specific performance. Separately, damage claims are also available in tort cases.

    Either in contract or in tort, if a party seeking compensation for monetary damages was also negligent, a Japanese Court may consider reducing damages under the concept of comparative negligence.

    Electronic signatures

    Act No. 102 as of 2000 on Electronic Signatures and Certification Business (Act) provides details regarding the enforceability of electronic signatures of individuals. Under the Act, documents with electronic signatures that meet certain requirements are acknowledged as authentically created by the signatories and are admissible as evidence in civil litigation. Electronic signatures are also available for corporations. Electronic signatures have been used in both public and private sectors in Japan, such as tax filings, biddings and commercial transactions.
