Chl a

Chlorophyll (Chl) d is expected to be oxidatively biosynthesizedfrom Chl a in plant, whereas the biosynthetic pathway of Chl d inAcaryochloris marina has not yet been clarified. We have alreadyreported the conversion of Chl a into Chl d with papain or withgrated papaya in aqueous acetone at room temperature in the dark.
Bromelain is also a proteolytic and thiol protease, a like papain,
and present in pineapple. In this paper, we examined the reactionof Chl a catalyzed by grated pineapple. Expected conversion of
Chl a → Chl d was not found, but novel conversion of Chl ainto 151-OH-lactone Chl a was observed. The lactonization
observed here is important in food science, since there is a needto control the stability of Chls in food processing.

they would like to know information by themselves, notfrom the assistant. The information includes the number of remaining pins, trajectory of the ball, andhow the ball hit pins. Therefore, to fill that needs, a support system which automatically detects
remaining pins and tells the number by computer voice was developed and tested by several blind
players as a first step. The system worked well and it can make the game more enjoyable tor thembecause it tells not only the number of remaining pins of the player but also of other players’ pins

Protecting your intellectual property by means of patentsRafaël H.L. Kiebooms,1
1)European Patent Office, The Netherlands
Patentlaan 2-9, 2288EE Rijswijk, The Netherlands, rkiebooms@epo.org
Introduction
Successful business needs intellectual property (IP) protection based on a combination of IP rights (e.g. copyrights,
design rights and patents), which provide detailed definitions of technical and artistic ideas and concepts. This IP rights
portfolio is used as a basis for value assessment of the intellectual assets of a company. Each country in Europe has its
own system for IP rights. For a uniform approach on patent rights, 38 European countries agreed to work together under
the European Patent Convention (EPC).
For the EPO to grant a European patent in respect of an invention, its description has to meet certain criteria. These arelaid down in the EPC and supported by the Guidelines for Examination, the latter being developed on the basis of thecase law of the boards of appeal. The most important criteria to be met are the requirements that the invention, as
defined in the patent application, is novel and involves an inventive step (Articles 54 and 56 EPC). These criteria areevaluated against the 'prior art', which consists of all knowledge made available to the public before the filing date of
the patent application, commonly in the form of a publication. The evaluation ('examination') of the technical criteria iscarried out in writing by an 'examining division' consisting of three technically qualified examiners (Article 18 EPC). If
the examining division intends to refuse a patent application, the procedure is concluded by a non-public hearing ('oral
proceedings'), which involves a highly technical assessment of the invention in view of scientific and technicalliterature to determine whether the patent application meets the EPC requirements. At the hearing the owner of theinvention, also called 'applicant' or 'proprietor', is usually represented by a patent attorney.
The protection of intellectual property is an important issue to support the return on investment in research anddevelopment. Patents are one of a number of important tools that allow intangible intellectual knowledge developed bycompanies and universities to be protected. For scientists and engineers it is important to know what constitutes apatentable invention and to have a general idea about the procedure to apply for a patent.
The criteria of patentability
The main categories of intellectual property rights are among others patents, trade marks, design rights and copy rights.
Patent rights are the main form of protection of scientific work. There are two major criteria which determine what is apatentable invention: the invention must be novel and must involve an inventive step. These criteria are applied
similarly throughout the global patent system. The general approach to evaluate these criteria will be explained for theinternational and European patent system while pointing out the parallelisms with the Japanese patent system.
Procedural aspects of filing a patent application
Each region or country has its own specific legal and procedural system. However, each patent system is characterized
by general common principles concerning the procedure of applying for a patent. The two important phases in theprocedure are, firstly, the investigation of the scientific literature published before the date of filing the patentapplication and, secondly, an examination of the patent application by a patent examiner in view of relevant prior art toestablish conformity with the local patent law system. Finally most patent systems provide the possibility to appeal arefusal of a patent application or for third parties to oppose a granted patent.
The international procedure of filing a patent application at the World Intellectual Property Organization (WIPO) is
usually followed by entering the regional (e.g. EU) and/or national (e.g JP or US) patent system. The procedure forfiling an international and European patent application before the European Patent Office will be used to illustrate thegeneral principles of filing a patent application.

The procedure to obtain the grant of a European patentRafaël H.L. Kiebooms,1
1)European Patent Office, The Netherlands
Patentlaan 2-9, 2288EE Rijswijk, The Netherlands, rkiebooms@epo.org
Introduction
he European patent grant procedure is an examination procedure beginning with a formalities examination and amandatory search. The first stage ends with the publication of the European patent application and the search report. At
the applicant's request this is followed by the second stage, substantive examination. After the patent has been granted,
there may be a further procedure in the form of opposition proceedings or, upon request of the patentee, limitation or
revocation proceedings.
The search report
On receiving an application the European Patent Office (EPO) examines whether it can be accorded a date of filing.
This is the case if the application documents contain: an indication that a European patent is sought; information
identifying the applicant; a description or a reference to a previously filed application. If the application has been
accorded a date of filing and is not deemed to be withdrawn, the Receiving Section checks for compliance with theprovisions governing translations, the content of the Request for Grant, the presence of claims, the filing of the abstract,
representation, formal requirements, any priority claimed, designation of the inventor and the filing of any drawings.
While the formalities examination is in progress, the European search is performed. The search report is drawn up on
the basis of the claims, with due regard to the description and any drawings. It mentions the documents available to the
EPO when it is drawn up which may be taken into consideration in assessing novelty and inventive step. The search
report is accompanied by an opinion on whether the application and the invention to which it relates meet therequirements of the European Patent Convention (EPC). The non-binding opinion is not published together with thesearch report but is available to the public by way of file inspection after publication of the application.
Substantive Examination
Once the request for examination has been filed, the EPO examines, in the light of the search report and the applicant's
response to it, whether the application and the invention to which it relates meet the requirements of the Convention,and in particular whether the invention is patentable. If the application and the invention to which it relates meet therequirements of the Convention, the examining division will decide to grant a European patent provided that therequisite fees have been paid in due time and a translation of the claims into the other two official languages of the EPO
has been filed in due time. The grant does not take effect until the date on which it is mentioned in the European Patent
Bulletin. At the same time as it publishes this mention, the EPO publishes a European patent specification containing
the description, the claims and any drawings. The European Patent Bulletin is published electronically on the EPO's
publication server (www.epo.org).
Opposition and Appeal
Up to nine months after publication of the mention that a European patent has been granted, anyone may give the EPO
notice of opposition to the patent. As a result of the examination of the opposition the opposition can be rejected, or thepatent can be maintained in amended form or be revoked.
Appeals may be filed against decisions of the Receiving Section, the examining divisions, the opposition divisions andthe Legal Division. An appeal has suspensive effect, which means that the contested decision is not yet final (no formal
res judicata) and its effects are suspended.

The seven deadly sins of the inventorRafaël H.L. Kiebooms,1
1)European Patent Office, The Netherlands
Patentlaan 2-9, 2288EE Rijswijk, The Netherlands, rkiebooms@epo.org
Introduction
There are many reasons why the application for the grant of a patent may not be successful. Even when apatent has been granted, the utilization of the patent may not provide the anticipated results.
Holistic intellectual property stragey
Obtaining a patent should be seen as one of the many pieces of a holistic Intellectual Property strategy. An
appropriate Intellectual Property strategy should consider the position of the organization in its
socio-economic ecosystem, the various possibilities to acquire intellectual property rights and finally how tobenefit form the utilization of the so-acquired intellectual property rights.
Establishing such a holistic strategy requires the close collaboration of experts not only in research anddevelopment, but also in marketing, management as well as the involvement of specialists in the different
intellectual property rights around the globe.
Seven deadly sins
There are many pitfalls during the acquisition of intellectual property rights such as patents but also
copyrights, design rights and trade marks. Among the many pitfalls, we highlight seven of some of thecommon issues that may either not yield a patent or lead to unsatisfactory utilization results. For an audience
with a scientific background, these issues are discussed in view of patents as a more pertinent intellectual
property right:
1. The invention is more complex than the problem merits
2. The invention is not kept secret until the date of filing
3. The invention is not new
4. The inventor has not fully considered the problem
5. No one is interested in the invention
6. An invention is not 'safer' when kept secret
7. The inventor has an unrealistic idea of his invention

Alkoxy substituent was introduced at 3,6-positions of poly(2,7-carbazole) to improve stability ofblue emission of organic light emitting diode (OLED). The polymer showed blue fluorescence but
the quantum yield was very low. It is thought that the polymer easily reacts with oxygen because ofa shallow HOMO level of the polymer. Therefore, HOMO levels and charge distributions of a seriesof polycarbazoles introduced alkoxy group are calculated by density functionary theory, andcompared each other. It is considered that reducing the charge at nitrogen is a strategy of design thistype of polymer for blue OLED.

Chl

Chl f

A Chl d-dominated cyanobacterium, Acaryochloris marina, wasdiscovered in 1993, but biosynthetic pathway of Chl d has not yet beenclarified. In 2010, a red-shifted chlorophyll was discovered in a methanolic
extract of Shark Bay stromatolites, and was named Chl f. In 2011, Chl f
was also discovered in a unicellular cyanobacterium isolated from Lake
Biwa, but Chl f was detected only when the cyanobacterium was cultivatedunder near infrared light. In order to clarify the birth of Chls d and f innature, we analysed pigments in processed vegetable foods: Chl d was
detected as a minor pigment in green juice, laver, green tea, powdery
parsley and basil. Chl f and Phe f were also detected in several green juice,tea and laver, while the amount was smaller than Chl d, suggesting the Chl
a → Chl f conversion is a little difficult than the Chl a → Chl d conversion.
Our finding indicates that the conversions from Chl a into Chls d and f are
not a rare event in nature, and will provide new insight into the unsolved
question as to the birth of Chls d and f in natural photosynthesis.

Precise physicochemical properties of divinyl chlorophylls werecompared with those of monovinyl Chls. With simple isocratic eluent
mode, DV- Chl b was clearly separated from MV- Chl b by anormal-phase HPLC, and pairs of DV- and MV-Chls a, a’, pheophytinsa were also well separated by a reversed-phase HPLC. Absorption
spectra of DV-Chls showed the red-shifted Soret band and the slightly
reduced QY band. The intensity of CD spectra of the DV-Chls were alittle smaller. Precise mass and NMR spectra of DV- and MV-Chls
were performed for the first time. The first oxidation and reduction
potentials of DV-Chl a were clarified to be very slightly more positive
than those of MV-Chl a by 8 mV and 10 mV, respectively.

A high-intensity mono-energetic positron beam generated by using a linear electron accelerator(linac) is used for total reflection high-energy positron diffraction (TRHEPD) researches at the Slow
Positron Facility, KEK. In contrast to the electron, the potential energy of the positron inside acrystal is positive, and hence positrons incident on a crystal surface at a glancing angle smaller thana certain critical angle are totally reflected. On the total reflection conditions, practically all the
positrons are reflected by the atoms that are exposed on the surface. This feature makes the
TRHEPD a structure analysis tool sensitive to the topmost layer of the crystal surface.
We show the TRHEPD diffraction pattern from the Si(111)-(7×7) surface without backgroundsignals from the bulk, which is obtained at a glancing angle smaller than the critical angle for the
total reflection. Details of the TRHEPD method and instrumentation are presented together withrecent results of its application to structure analysis on the Pt/Ge(001) nano-wire surface,TiO2(110)-(1×2) surface, and silicene on Ag(111) surface.

We recently reported that anthracene compound withappropriate substituent (Fig. 1, n = 6) showed phase change
behavior (between crystalline and amorphous) by the action oflight. In this study, we synthesized analogous compounds (n =2-10) and investigated their properties. Interestingly, it was
found that anthracene compounds with odd numbers of n
showed liquid-crystalline (LC) phase but not photoinduced
phase change, in contrast, the compounds with even numbersof n exhibited photoinduced phase change but not LC phase.
