STEPS FOR OBTAINING PATENT

GANESH BABRUWAN JAMBALDARE

ABSTRACT

A patent is one of the forms in intellectual property. The object of product law is to encourage scientific research, new technology and industrial process. The grant of exclusive privilege to own, use or sell the method or product patented for limited period, stimulates new inventors of commercial utility. The price of the grant of the monopoly is the disclosure of the inventing at the patent office, which after the expiry of the period of monopoly, passes into push domain. An invention which must be new and a useful. It must have novelty and utility. The patent are granted to encourage inventions and to secure that the invention are worked in India on a commercial scale and to the fullest extent that is reasonable practicable without undue delay. So true inventor required to know how to ret patent in India and other countries through his self or legal representative. Without patent no one use, sell and research an invention.

Keywords :- Patent, patent history, Patent Application, processing an Application, Patenting  abroad.

SIGNIFICANCE OF IP SYSTEM IN ACADEMICS

DR. NIRMAL SAHUJI & DR. RAGAVENDRA TOPARE

ABSTRACT

Govt agencies like NAAC, NIRF, ARIIA  assess and accredit educational institutions rank and give special attention to explore  Intellectual property( IP) Education being imparted to both  students and staff. Universities and colleges disseminate the knowledge through research carried out in their laboratories and through teaching. In the era of globalization, through internet, one can retrieve information just with a click. As far as teaching and research is concerned, one can use open access publication but same may not be true for laboratory finding and research. Such findings need to be confidential so that it can be patented and developed commercially. To manage the IP derived from their own research, government grant rights to their IP so that universities and colleges can convert invention in to commercialise product.  This may also lead to strengthening the industry-institute linkage which is really need of the time. In the present paper, the need for Institute to understand how to use IP system and to run a IP center in campus with well defined IP policies is discussed.

NEED AND IMPORTANCE OF INTELLECTUAL PROPERTY

DHANAJI ARYA & ATKARE KAILASH ANKUSHRAO

ABSTRACT

Intellectual Property refers to intellectual creativity of a creator. In contrast to physical property, intellectual property is an intangible asset of a person. Intellectual Property Rights (IPR) is the exclusive rights given to the creators to their creations. Common types of Intellectual Property Rights are patents, copyrights, trademarks, industrial deigns, geographical indications, trade secrets, layout designs for integrated circuits and even ideas. Intellectual property rights provide an incentive to the creator to develop his creation and to share it with other people for the development of the society. The basic aim of the IPRs is to help in meeting the challenges in the development like reducing poverty, stimulating economic growth, improving the health status by providing medicines to the poor, improving access to education and contributing the overall sustainable development. Though IPRs provide incentive to the author or the creator and lead to a competition in the field of invention but it is also an intellectual protectionism or a form of a temporary monopoly enforced by the state.

Keywords: Intellectual Property, Intellectual Property Rights, patents, copyrights, trademarks, geographical indications.

CONTOURS AND NUANCES OF INTELLECTUAL PROPERTY RIGHTS, COPY RIGHTS AND PATENTS: A FEW EXPLORATIONS

DR. SANJAY B. SALUNKE & DR. NAVLE BALAJI ANANDRAO

ABSTRACT

The cardinal concepts such as ‘intellectual property rights,’ ‘copy rights’ ‘trademarks’ and ‘patents’ is generally connected with a special kind of property known as ‘intellectual property’ (IP). ‘Intellectual property’ is a special wealth and power acquired by human beings out of an infinite and perpetual capacity of hard work. The term, ‘intellectual property’ first came into being in the 19th century, but only became commonly used towards the end of the 20th century. The World Intellectual Property Organization (WIPO) was founded in 1967 as a specialized agency of the United Nations with its headquarters in Geneva, Switzerland. WIPO is mandated with ensuring that an international system of IP is established to safeguard and protect creativity in a balanced and appropriate manner. In June 2000, the Policy Advisory Commission (PAC) of the World Intellectual Property Organization (WIPO), namely WIPO-PAC, met in Geneva to define and refine policy related to intellectual property. The idea of intellectual property came into being as early as 1883. Concern had been raised a few years earlier, when a group of creators would not participate in the International Exhibition of Inventions in Vienna for fear of their ideas being stolen.

HISTORY OF INTELLECTUAL PROPERTY RIGHTS AND ITS ROLE

DR. NILIMA RAJENDRA BANKAR

ABSTRACT

The rapidly changing scenario and India’s continuing progress towards economic upliftment and globalization through liberalized policy make it imperative that the potential beneficiaries of the Intellectual Property Right (IPR) system familiarize themselves with basic elements of IPR to maximize their exploitation. According to Dr. R. A. Mashelkar, the director General, CSIR (India) in his article published in journal of chartered Secretary (Jan. 2002) felt that “Twenty first century will be the century of knowledge. A nation’s ability to convert knowledge into wealth and social good through the process of innovation, will determine its future. In this context, Issues like generation, valuation, protection and exploitation of intellectual property (IP) are going to become critically important all around the world. Exponential growth of scientific knowledge, increasing demands for new forms of intellectual property protection as well as access to IP related information, increasing dominance of the new knowledge economy over the old brick and mortar economy, complexities linked to IP in traditional knowledge, community knowledge and animate objects, will pose a challenge in setting the new 21 century IP agenda.

TYPES OF INTELLECTUAL PROPERTY RIGHTS

DR. CHOUDHARI REKHA LAXMANRAO

ABSTRACT

Intellectual property, very broadly, means the legal rights which result from intellectual activity in the industrial, scientific, literary and artistic fields. Countries have laws to protect intellectual property for two main reasons. One is to give statutory expression to the moral and economic rights of creators in their creations and the rights of the public in access to those creations. The second is to promote, as a deliberate act of Government policy, creativity and the dissemination and application of its results and to encourage fair trading which would contribute to economic and social development. 1.2 Generally speaking, intellectual property law aims at safeguarding creators and other producers of intellectual goods and services by granting them certain time-limited rights to control the use made of those productions. Those rights do not apply to the physical object in which the creation may be embodied but instead to the intellectual creation as such.

SIGNIFICANCE OF INTELLECTUAL PROPERTY RIGHTS AND COPYRIGHT

DR. AHILYA BHARATRAO BARURE

ABSTRACT

India has an ancient and great tradition of knowledge benefaction. It is considered as the best and topmost benefaction. India has an intellectual heritage in the fields of literature, research, intellectual skills in software designing and also in missile technology. At the initial stage the concept of intellectual property rights was not rooted very easily in India. But when the news of Basmati Rice and turmeric patent spread people started to think about the intellectual property rights. At that time different ideologies came in to existence like there has been a lot of controversy on the role of intellectual property rights. Some said copyright is a kind of protectionism it will lead to monopoly which may be obstacle in public interest and specific needs of the country. The present paper aims to focus on the importance of intellectual property rights and infringement of copyright as a violation of intellectual property rights. The intellectual property rights are territorial rights by which owner can sell, buy or license his intellectual property similar to physical property.

INTRODUCTION TO INTELLECTUAL PROPERTY RIGHTS (IPR)

WARVATE SADASHIV BALASAHEB

ABSTRACT

Intellectual property rights are like any other property rights – they allow the creator, or owner, of a patent, trademark, or copyright to benefit from his or her own work or investment. These rights are outlined in Article 27 of the Universal Declaration of Human Rights, which sets forth the right to benefit from the protection of moral and material interests resulting from authorship of any scientific, literary, or artistic production. The importance of intellectual property was first recognized in the Paris Convention for the Protection of Industrial Property in 1883 and the Berne Convention for the Protection of Literary and Artistic Works in 1886. Both treaties are administered by the World Intellectual Property Organization (WIPO).Intellectual property refers tocreations of the mind: inventions, literary and artistic works, and symbols, names, and images used in commerce. Intellectual property is divided into two categories: Industrial Property includes patents for inventions, trademarks, industrial designs and geographical indications. Copyright includes literary works such as novels, poems and plays, films, musical works, artistic works such as drawings, paintings, photographs and sculptures, and architectural designs. Rights related to copyright include those of performing artists in their performances, producers of phonograms, and those of broadcasters in their radio and television programs.

SIGNIFICANCE OF INTELLECTUAL PROPERTY RIGHTS

DR. D. N. GANJEWAR & DR. CHALINDRAWAR GANESH KISHANRAO

ABSTRACT

God gifted a wonderful thing called Brain to Man and Mother Nature endowed him with the abundant physical and biological resources on the earth. Man started creating his own world by application of his brain or mind and by utilization of these natural resources. Man has also been bestowed with imagination and creativity. With his imagination and creativity, he has been producing various articles or products for his needs, comfort and convenience. In the earlier era, the creations and inventions by him fell in a public domain. These were the common properties. Anybody could use and copy these creations and inventions without any restriction, reservation or payment. However, with the passage of time, the importance and value of these creations was realized. The commercial aspect started playing a significant role in these creations. By end of Twentieth Century, the things created and invented by the human mind were recognized as an intellectual property of the owner .The owner's right over these properties was accepted and is known as an Intellectual Property Right (commonly called I.P.R.). A new set of laws called Intellectual Property Right Laws, were enacted to protect these property rights. These I.P.R. laws provided a protection to the owners under different categories and names like Patents, Industrial designs, Copyrights, Trade- Marks etc.

INDIAN CULTURE DEPICTED IN MODERN INDIAN FICTION

DR. D. N. GANJEWAR & KUCHEKAR SHAILAJA BABURAO

ABSTRACT

India, with its rich heritage is well identified for its unity in diversity. People from different religion, caste, language and custom live together. Different religions have different culture, and they follow it with keeping its greatness alive. This is the only country which has accepted cultural diversities and follows them. Thus the nation represents ideal integrity. As India has agreed with all the customs and traditions it becomes the nation of multiculturalism. Multiculturalism is not only seen in religious ceremonies but also in literary works produced in India. Indian literature has been produced in various regional languages. Right from Sanskrit to foreign language like English is being used for creating literary works. Initially, Bengali writers started translating their Bengali works into English. Then literary works were being written in English. Other regional writers also tried their hands in English. Many Indian writers have created wonderful works in English.

ATUL P. KECHE, ASHOK V. HUMBE, S. S. DESHMUKH, MANISHA R. PATIL, M. N. SARNAIK, S. J. SHUKLA, K. M. JADHAV

ABSTRACT

In the present work, influence of varying particle size of cadmium ferrite nanoparticles synthesized via ceramic and sol-gel auto combustion method on the structure and magnetic properties is reported. Cadmium ferrite in bulk and nanosize form was prepared by ceramic technique using AR grade oxides of respective ions (CdO and Fe2O3) and sol-gel auto combustion method using AR grade nitrates of respective ions (Cd (NO3)2 • 6H2O and Fe (NO3)3 • 9H2O). The X-ray diffraction technique was used to study the structure while pulse hysteresis loop technique was used to study the magnetic properties. The analysis of XRD patterns reveals the formation of single phase cubic spinel structure. The XRD data was used to obtain the particle size. The particle size of the ceramically and sol-gel synthesized CdFe2O4 calculated using Scherrer’s formula was found to be – nm and – nm respectively. The lattice constant of both the samples is in reported range. The M-H hysteresis curve shows remarkable changes in saturation magnetization and coercivity. Thus, the particle size shows strong influence on the structure and the magnetic properties of cadmium ferrite.

STRUCTURAL AND DYNAMIC PROPERTIES OF POLAR LIQUIDS USING TIME DOMAIN REFLECTOMETRY IN MICROWAVE FREQUENCY

V. P. PAWAR, SHAGUFTA TABASSUM

ABSTRACT

The complex permittivity spectra and thermodynamic properties of 1,2-dichloroethane (DE) and n,n-dimethylformamide (DMF) has been obtained at 15°C temperature in the frequency range of 10 MHz to 30 GHz by using time domain reflectometry technique for 11 different concentrations of the system. A complex spectrum gives information regarding dielectric dispersion (ɛʹ) and dielectric absorption (ɛʺ), which indicates the purity of the liquid mixture. In binary mixture of polar liquids mixed together, there is a change in the energy of the system. This change in energy can be interpreted with thermodynamic parameters such as free energy of activation (DG), molar enthalpy of activation (DH) and molar entropy of activation (DS).

INFLUENCE OF CADMIUM SUBSTITUTION ON DIELECTRIC PROPERTIES OF NI-Cu FERRITES

R. B. KAVADE, R. G. VIDHATE, J. M. BHANDARI, S. J. SHUKLA, K. M. JADHAV

ABSTRACT

The Cd2+ions substituted samples of mixed nickel- copper ferrites having the compositional combination Ni0.5Cu0.5-xCdxFe2O4 (x = 0.0, 0.1, 0.3, 0.5) have been synthesized using AR grade oxides by standard solid state reaction technique. The formation of single phase cubic spinel structure of all the samples under investigation have been carried out using X-ray diffraction technique at room temperature. Using LCR–Q meter the dielectric constant (ε′), dielectric loss (ε″), dielectric loss tangent (tand) was measured as a function of frequency. The frequency dependence of dielectric parameters measurements was carried out within the range 100 Hz to 1 MHz. The values of dielectric parameters (e¢,e²and tand)are much higher at lower frequencies but decreases with increase in frequency. At very high frequencies, its values become so small that it becomes independent of frequency. The decrease in dielectric parameters with increase of frequency may be due to the fact that beyond a certain frequency of the external electric field, the electronic exchange between ferrous and ferric ions cannot follow the alternating field. It is observed that dielectric constant (e¢), dielectric loss (e²) and dielectric loss tangent (tand) appreciably increases with cadmium concentration x but decreases with increases in frequency.

The X-ray analysis confirmed the formation of single phase cubic spinel structure. The mass attenuation coefficient, total atomic cross section and total electronic cross-section of Ni0.3Zn0.5Cu0.2Fe2O4 spinel ferrite have been obtained using narrow beam technique as a function of varying thickness. The results show that as thickness increases all these parameters decreases. XCOM program was used to obtain the theoretical values of mass attenuation coefficient.
