Got a DMCA notice for copyright infringement

Dear Taher Naalwala,
I am just attaching few paras for your reading.
See what is applicable.
Copyright is a well-known type of intellectual property (IP) protection represented by the © symbol. Watch any film and the copyright infringement warning will appear, threatening jail time and fines. Copyright extends beyond video to songs, pictures, books, blogs, podcasts, paintings and even software. For those who are both consumers and business owners, it’s important to know how to avoid copyright infringement.
Copyright laws are designed to protect the creator of original works, which are creative expressions from others using and profiting their work, without permission. The idea is that the author or creator owns the rights to the work and can decide if and how others use his or her creation.
For example, music copyright would exist for songwriters on their lyrics. When songwriters allow artists to record their words, there would be an agreement outlining how the right to record is granted, thus avoiding copyright infringement.
If another artist decided to record the same song without permission, the songwriter would be able to bring legal action for copyright infringement against the artist. If you believe that the copyright infringement definition sounds like stealing, you would be correct.
Other examples of copyright infringement include:
 Downloading movies and music without proper payment for use
 Recording movies in a theater
 Using others’ photographs for a blog without permission
 Copying software code without giving proper credit
 Creating videos with unlicensed music clips
 Copying books, blogs or podcasts without permission
 Anything where you are copying someone else’s original work without an agreement

If you are confidant then argue it in the Court of Law.
If are not, then hire the services of a copy right Advocate who will defend you and try to appear in the Court and take time for reply.
Shanti Ranjan Behera,
Advocate
