How would you characterize the overall appropriability of the float glass process using the vocabulary of the class?

The most important parts of the case are in the first 14 pages (up the the “Diversification” section header), so read those and just quickly skim the rest. In 300 to 500 words, answer the following questions:
1. How would you characterize the overall appropriability of the float glass process using the vocabulary of the class?
2. Describe Pilkington’s commercialization strategy for float glass. What were the complementary assets and how did Pilkington get them? Was Pilkington successful in establishing float as a dominant design? Would you have followed a different strategy if you were in charge?
I attached the PPT and case below. Thank you
