It wouldn't matter how you classified the cost of development as you suggest.
They would have been shown as intangible assets which would have been written off over some period of time. How much of the total cost allocated to the patents is a question, butstill in the long run all of the costs would hit the income statement.
The write off mayhave been calculated over the life of the patent, thus we would satill have a portion of the total paid in capital left to write off.
None of the invested capital would stay as long term assets as you suggest.
The 80 million deficit is correct or would be after the patents had expired.
And on;ly a portion of the total paid in amount could even be allocated to the cost of patents. The other costs would include salaries, and many other expenses not associated with the patentsd.
