Dear Amit Sharma,
I had yesterday given you a clear cut reply. If you are looking at a process wherein you can circle round the terms and conditions of the company you are working for, then you shall be calling for trouble.
If the product or process is invented during your tenure in the office (IT Company), then the proprietary right is of the company you work for.
Further, there is no legal way to circle round and obtain the patent in your name. However, you can negotiate with your company about the percentage claim in the patent that you have invented, that is another issue. There is no way you can be the owner of the patent if the applicant is your company. You can be the owner if you file for the patent in your name which you can do without letting the company know and keep it confidential till your patent is filed and published which will be highly unethical and will be not as per law. However, the troubles that you will be looking for are:
1) Your company will know once the patent is published and you may stand to lose your job.
2) You many attract penal action by your company
3) You may be jailed
Further, if your company gets a patent, then you cannot sell the rights of your product to anyone else as you do not have any right over the patent.
What best you can do is talk with out with your company to license your invention to them on a royalty basis for 20 years. That's the best you can do because what you are trying to do here is commit an offence of cheating your company. It was the company's resources that you used to develop the idea or the patent, even if you didn't use the company's resources, the invention clicked into your mind because of a lacunae that you might have observed during a project or in general during your working in the company which legally means that the patent if granted is of the company.
And my humble request to you Mr. Sharma is not to indulge in any unlawful activities rather talk it out with your company for a license fee or a bigger percentage in royalty.
I hope good sense prevail on you and may you succeed to create more inventions.
I hope the above satisfies your question
