Analysis of patents related to CNT synthesis via CVD and fluidised bed CVD (FBCVD).

Main Results:

The CNT patent space is convoluted and uncertain, creating a 'patent thicket'.
Fluidised bed chemical vapor deposition (FBCVD) is identified as a promising method for large-scale, low-cost CNT production.
Potential for future litigation to resolve intellectual property ownership is high.

Conclusions:

The current patent thicket poses significant challenges to the commercialization of large-scale CNT synthesis.
Clarification of intellectual property rights is needed to foster innovation and market growth in CNT technology.
Navigating the complex patent landscape is essential for companies involved in CNT production and application.
