Welcome to the website of Inoue & Associates

Introductory Statement

Inoue & Associates (located within 1 minute walk from the Japan Patent Office) is an intellectual property (IP) firm having more than 35 years of experience in international IP business.

We are a modest-sized IP firm composed of members each having profound knowledge about the legal aspect of IP and the technologies involved therein as well as excellent skill in actual IP practice, such that high quality services can be offered constantly at a reasonable price.  Each one of our staff members is so trained as to be able to always provide high quality IP-related services including production of documents having a clear and logical construction whether they are in English or Japanese and irrespective of urgency or technical difficulties involved in particular cases.

Over the years, we have built up a solid reputation for our ability to efficiently acquire and protect IP rights in Japan.

We are confident that we can provide higher quality IP services than any other IP firms in Japan.

Features of Inoue & Associates

For acquiring and protecting patent rights, everything starts from the claims and specification of a patent application or a granted patent.  Whether a patent application can be granted with a desired protective scope or a granted patent can survive the challenge from a third party depends utterly on how good the claims and specification have been drafted in the first place.

Invalidation of patents, unexpectedly narrow scope of protection, defeat in infringement suit … all such undesired outcome could have been avoided only if the patent application had been better drafted. 

In the case of Japanese patent applications filed by non-Japanese entities, the claims and specification are usually translations from the non-Japanese texts of the first filed foreign applications or PCT applications. 

From this perspective, the translation of the patent claims and specification is actually more than just a translation and is practically tantamount to the preparation of a legal document which serves as a basis for seeking patent protection.  For this reason, the translation should be done with utmost care by IP professionals such as experienced patent attorneys or paralegals

And that is what we do and is not done by most of the IP firms in Japan


Problems related to traditional way of handling patent applications from outside Japan

In typical Japanese IP firms, applications from foreign clients are handled by a team of an IP professional (a patent attorney or a paralegal) and a translator. For example, the translation of a PCT specification for the Japan national phase entry is often carried out by one who is the least experienced in the IP firm or even by an outside translator.

The IP professions work on legal matters based on the translations prepared by translators which are not always so good or of a rather poor quality in many cases. This manner of handling patents is disadvantageous not only from the aspect of efficiency but also from the aspect of cost because poor translations of course make the entire procedure unnecessarily complicated and high translation fees are required even if the translations are not so good. Such inefficient and problematic practice as mentioned above has become customary because many Japanese IP professionals are not good at writing in English or even reading English documents, and the English-to-Japanese translations are generally assigned to beginners.

Consequently, many Japanese IP professionals have to rely on poor translations in their works, thus falling into a vicious cycle. It is not surprising even if patent applications from foreign clients are handled by those who do not fully understand what is disclosed in the original specification nor the clients’ instructions given in English during the prosecution of the application. For years, this has been a serious problem as far as the patent applications from outside Japan are concerned.

Our Solution

Such problems as mentioned above will never happen in the case of Inoue & Associates. Every one of our staff members has gone through very hard training and long actual experience to acquire ability to handle the IP cases alone from drafting patent specifications whether they are in Japanese or English to dealing with various procedures relating to patent applications or registered patents. We do not need and actually do not use any translator. Even in the case of foreign patent applications (in US, EP etc.) filed by Japanese applicants through our firm, the US or European patent attorneys often use our draft documents without any substantial change. That is, the documents drafted by Inoue & Associates as such are often submitted to the USPTO or the EPO.

There is no magic formula for acquiring good IP rights. This can be achieved only by hard work and skill obtainable through long and rich experience as always required in any fields for realizing high quality services.

Inoue & Associates is one of the very limited number of Japanese IP firms capable of constantly offering high quality IP services at a reasonable price. There has been and will be no compromise in the quality of services we provide to our clients and, for this very reason, we have been trusted by many foreign clients as well as domestic clients.

Our skill in IP business is highly esteemed by our clients including two famous Japanese professors emeriti, Dr. Nobuatsu Watanabe and Dr. Hidefumi Hirai, whose recommendations are shown in this web site. Further, if requested, we will be able to show you copies of some letters from various US and EP attorneys praising our abilities.

Our highly-skilled staff members will surely be of great help to your establishment of strong and valuable intellectual property portfolio while reducing cost.

If you are not sure, try us and we promise that we will never fall short of your expectations. You will immediately realize that we are dedicated to efficient acquisition and protection of your valuable intellectual properties and have skills to achieve this goal.

For activating a MAPK kinase, it is necessary to phosphorylate two serine and/or threonine residues (i.e., two serine residues, two threonine residues, or one serine residue and one threonine residue) located in the boundary region between the kinase subdomains VII and VIII, and a serine/threonine kinase responsible for this phosphorylation is designated MAPKK kinase (MAPKKK). The above-mentioned Raf-1 is one example of MAPKK kinase, and the following cascade reaction: Ras → Raf-1 (i.e., MAPKKK) → MAPKK → MAPK, is one of the major signal transduction pathways. The cascade reaction consisting of three kinase molecules, MAPKKK → MAPKK → MAPK, is called a MAP kinase signal cascade.

SIIS-1発現プラスミドの構築上記(ii)で単離したSIIS-1cDNAを制限酵素XbalとPvuIIで消化し、得られた制限酵素断片をブラントエンド化し、哺乳動物発現ベクターpEF-BOSのブラントエンド化したXbalサイトに挿入した。以下、構築したSIIS-1発現ベクターをpEF-BOS/SIIS-1(SH+)とする。SH2領域を欠損した変異型SIIS-1を構築するために、pEF-BOS/SIIS-1(SH+)を制限酵素BssHIIで消化し、生じた360bpの断片を除去した。得られたSH2領 域及びC末端の領域を欠損したSIIS-1発現ベクター(即ち、SIIS-1変異ベクター)を、pEF-BOS/SIIS-1(SH-)とした。 上記で構築したpEF-BOS/SIIS-1(SH+)又はpEF-BOS/SIIS-1(SH-)のいずれか一方の発現ベクターとネオマイシン耐性遺伝子をコードするpSV2 Neoとを20:1の比率で混ぜ、M1細胞にエレクトロポレーション法で形質導入した。ネオマイシン耐性を指標とし、形質導入体(クローン)をGeneticin(米国、GIBCOBRL社製)750μg/mlを含む成長培地中で選択した。


Construction of SIIS-1 expression vectors: SIIS-1 cDNA isolated in step (ii) above was digested with restriction enzymes XbaI and PvuII, and the end of the obtained restriction fragment (XbaI-PvuII) was converted into a blunt end. Then, the resultant blunt-ended fragment was inserted into the blunt-ended XbaI site of the mammalian expression vector pEF-BOS. Hereinafter, the constructed SIIS-1 expression vector is simply referred to as "pEF-BOS/SIIS-1 (SH+)". For the construction of a mutant SIIS-1 which is an SH2 domain-deficient SIIS-1, a BssHII-digested fragment of 360 bp was removed from pEF-BOS/SIIS-1 (SH+). The thus obtained SIIS-1 expression vector (that is, a mutant SIIS-1 vector) which is deficient in the SH2 domain and is truncated at the C-terminus is hereinafter simply referred to as "pEF-BOS/SIIS-1 (SH-)". Each of the expression vectors pEF-BOS/SIIS-1 (SH+) and pEF-BOS/SIIS-1 (SH-) prepared above was individually mixed with expression vector pSV2 Neo (encoding a neomycin-resistance gene) at a ratio of 20:1. Subsequently, each of the resultant vector mixtures was separately transfected into M1 cells by electroporation. Using neomycin resistance as an index, the transfectants (i.e., clones) were selected in the growth medium containing Geneticin (manufactured and sold by GIBCO BRL, USA) at 750 μg/ml.

文明社会はエネルギーの消費によって成立するが、そのエネルギーの大部分は、自然が長年か けて太陽光エネルギーを蓄えた化石燃料に由来する。近年、その化石燃料の減少やその燃焼に よる地球温暖化問題が、人類社会の持続的発展の足かせとなる危惧が高まっている。 これらの問題を解決するために、太陽エネルギーから直接エネルギーを取り出す研究開発が盛 んに行われている。これらの中で、太陽電池は太陽エネルギーからのエネルギー取り出し効率 (エネルギー変換効率)が高いため多くの研究が為されている。とりわけ、色素に代表される光 増感剤を用い、その励起電子を効率よく取り出すことが可能な色素増感型太陽電池は、Michae l Gratzel等によって、エネルギー変換効率が7%を超えるシステムが発表(Nature 1991,353,737参照)されて以来、複雑な製造工程を経ず、安価に製造できる次世代の太陽 電池として注目を集めている。


Consumption of energy is indispensable to civilized society. Most of the energy which is consumed by civilized society is derived from fossil fuels, in which sunray energy has been accumulated over many years. In recent years, the problem that the amount of fossil fuels available is being reduced and the problem that the burning of fossil fuels causes global warming have arisen, and there is an increasing fear that these problems will be obstacles to the sustainable development of human society. For solving the above-mentioned problems, various studies have been made to directly utilize sunray energy. Among these studies, the studies on solar batteries have been vigorously made, because solar batteries exhibit high efficiency in converting solar energy to electric energy (i.e., high energy conversion efficiency). Among the solar batteries, special attention has been paid to a dye sensitized solar battery, which uses a photosensitizer, such as a dye, and which is capable of efficiently taking out electrons from the photosensitizer by the irradiation of the photosensitizer with sunray. Specifically, since Michael Gratzel et al. reported a system which uses a dye sensitized solar battery having an energy conversion efficiency of more than 7 % (see Nature 1991, 353, 737), a dye sensitized solar battery has drawn special attention as the next generation solar battery which can be produced at a low cost without use of a complicated method.
