I have no money. This is one of the most common legal problems around. The inventor has good evidence that his or her invention has been copied or patent infringed and yet cannot obtain access to justice because the infringer is a huge company, with massive assets and a large in-house legal department, and the inventor cannot fund litigation. This would restrain a defendant infringing up to trial when the matter could be finally solved. First check whether you are insured for legal costs.
Many companies now have legal expenses insurance.
Check exactly what the cover comprises and any financial limits. Secondly, consider taking out special intellectual property infringement insurance. Finally, if you are on income support or have a very low income indeed, you may be eligible for legal aid. This will be subject to a state means and merits test. If no assistance is available consider litigating yourself.
