Context: Copyright refers to the legal right of the owner of intellectual property. In simpler terms, copyright is the right to copy. This means that the original creators of products and anyone they give authorization to are the only ones with the exclusive right to reproduce the work.
Copyright law gives creators of original material the exclusive right to further use and duplicate that material for a given amount of time. Once a copyright expires, the copyrighted item becomes public domain.
Legal Provision Available Regarding Copyright Infringement
- Copyright ensures certain minimum safeguards of the rights of authors over their creations, thereby protecting and rewarding creativity.
- Copyright Act of 1957, protects original literary, dramatic, musical and artistic works and cinematograph films and sound recordings from unauthorized uses.
- Literary, dramatic, musical or artistic works enjoy protection for the life time of the author plus 60 years beyond i.e. 60 years after his death.
- In case of joint authorship, the term of copyright is to be construed as a reference to the author who dies at last.
- It gives broadcasting reproduction right to every broadcaster which is valid for 25 years from the beginning of the calendar year next following the year in the broadcast has been done.
- Copyright Board Act provides for the establishment of the Copyright Board and empowers Central Government to constitute the same for settlement of disputes, granting of licenses, etc.
- The copyright infringement is punishable with imprisonment for a term which may extend up to 3 years.
Issues With the Act
- A copyright is created the moment a piece of art or music or literature is fixed on a medium, provided it is original.
- Unlike trademark law, it is not mandatory under the Copyright Act to register copyrights as a necessary precondition in order to enforce the same.
- Whether the piece of art or music or literature is original or not is another complicated question of law.
- There is the question of whether the use of the copyrighted work is permissible under all the provisions in Section 52 of the Copyright Act outlining the exceptions to copyright infringement.
- For example, if a work is qualified for protection under the Designs Act of 2000, it can no longer claim protection under the Copyright Act once it is reproduced beyond a certain threshold.
- Determining the copyright infringement would require the court to apply the test of substantial similarity on a case-by-case basis.
Supreme Court Judgements
- In the Knit Pro International v. The State of NCT, the SC held that the offence of copyright infringement under Section 63 of the Copyright Act is a cognizable and non ¬bailable offence.
- The bench held that if the offence is punishable with imprisonment for three years and onwards but not more than seven years (3-7 years), the offence is a cognizable offence.
- As a result, it takes away the right of the accused to post a bail bond with the police and shifts the responsibility on to the courts for judicial determination on a case-by-case basis.
- Cr.P.C. defines cognizable offence as an offence for which the police officer can arrest the convict without a warrant and can start investigation without the due permission of the court.These are the offences that are usually very serious and generally heinous in nature such as rape, murder, kidnapping, dowry death etc.

Context: CAR-T cell therapy (Chimeric Antigen Receptor T-cell therapy) is a groundbreaking immunotherapy approach used to treat certain types of cancer, primarily hematological malignancies like B-cell lymphomas and leukemia. This therapy involves the genetic engineering of a patient’s own T cells to recognize and attack cancer cells. As per the Globocan estimates, the cancer burden worldwide is expected to be 28.4 million cases in 2040, a 47% rise from 2020, due to demographic changes.
How Does it Work?
- T cells are white blood cells responsible for identifying and fighting illness and infection.
- Each T cell has a receptor that can recognize antigens (proteins or molecules recognized by the immune system).
- Cancer cells may have antigens that the immune system does not recognize as abnormal, allowing cancer to evade the immune response.
- CAR-T cells are genetically engineered in the lab to express a new receptor that can bind to cancer cells and effectively kill them.
- The process involves several steps, including:
- Collecting T Cells: Blood is drawn from the patient’s arm, and T cells are separated from the blood using an apheresis machine.
- Engineering T Cells: In a laboratory, the T cells are modified by adding a manufactured CAR, and they are allowed to multiply and grow.
- Infusing CAR-T Cells: Once enough CAR-T cells are prepared, they are injected back into the patient’s arm.
- Chemotherapy may be recommended before CAR-T cell infusion to enhance treatment effectiveness.
- The process can take place in an outpatient infusion center or a hospital setting.
- CAR-T cell therapy is effective against certain types of cancer, especially when other treatments are ineffective.
- It is currently FDA-approved for treating hematological malignancies, including leukemia, lymphoma, and multiple myeloma.
Significance
- CAR T-cell therapies are even more specific than targeted agents and directly stimulate the patient’s immune system to fight cancer, leading to greater clinical efficacy.
- That’s why they’re referred to as “living drugs.”
Challenges
- Preparation: The difficulty of preparing CAR T-cell therapies has been a major hindrance to their widespread use. The first successful clinical trial was published a decade ago, and the first indigenously developed therapy in India was performed in 2021.
- Side Effects: In certain kinds of leukaemias and lymphomas, the efficacy is as high as 90%, whereas in other types of cancers it is significantly lower. The potential side-effects are also significant, associated with cytokine release syndrome (a widespread activation of the immune system and collateral damage to the body’s normal cells) and neurological symptoms (severe confusion, seizures, and speech impairment).
- Affordability: Introduction of CAR T-cell therapy in India can face challenges of cost and value. Critics argue that developing CAR T-cell therapy in India may not be cost-effective as it will still be unaffordable for most people.
What Are T Cells?
- T cells, also known as T lymphocytes, are a type of white blood cell that play a central role in the immune response.
- T cells are involved in cell-mediated immunity, which means they help the body recognize and respond to foreign substances, such as viruses, bacteria, and abnormal cells, such as cancer cells.
- There are two major types of T cells, the helper T cell and the cytotoxic T cell. As the names suggest, helper T cells ‘help’ other cells of the immune system, whilst cytotoxic T cells kill virally infected cells and tumors.
Government Initiatives Related to Cancer Treatment
- National Programme for Prevention and Control of Cancer, Diabetes, Cardiovascular Diseases and Stroke: Launched with the aim to prevent and control these diseases thorough awareness generation, behaviour and life-style changes, early diagnosis of persons with high levels of risk factors.
- National Cancer Grid: Formed in 2012, it is a network of major cancer centers, research institutes, patient groups and charitable institutions across India with the mandate of establishing uniform standards of patient care for prevention, diagnosis, and treatment of cancer, providing specialized training and education in oncology and facilitating collaborative basic, translational and clinical research in cancer.
- National Cancer Awareness Day: 7th November in India every year since 2014 to create public awareness about early detection, prevention, and treatment of cancer.
CONCLUSION
CAR T-cell therapy is a promising and innovative approach to treating cancer. It involves the genetic modification of a patient’s T cells to create chimeric antigen receptors (CARs) that target specific cancer cells. This treatment has shown great promise in clinical trials and has already been approved for the treatment of certain types of leukaemia and lymphoma.
