I would like to hire a capable law firm to handle a potential case of trademark passing off against another registered trademark holder. Additionally, there may be several rectification proceedings involved. Considering the extensive scope of this potential assignment and the advice I have received, it would be financially burdensome to pay for each hearing and draft individually. I have noticed that lawyers in Chandigarh charge a fixed fee for the entire case. Do lawyers in Delhi follow the same practice? I have been contemplating the idea of a monthly retainer for each lawsuit or rectification. Is it common for IP lawyers in Delhi to work on a monthly retainer basis? If so, what are their typical charges in such cases? Are there other cost-effective mechanisms out there worth considering? Is there scope for litigation financing for such disputes?
