| Abstract: | Relatively flat US productivity growth versus rising R&D expenditures is often interpreted as evidence that ideas are getting harder to find. We build a new 45-year panel tracking the universe of US firms' patenting to investigate the micro underpinnings of this conclusion, separately examining the relationships between research inputs and ideas (patents) versus ideas and growth. We find that average patents per R&D input are increasing, the elasticity of patents to R&D inputs is flat or rising, and there is not systematic evidence of a secular decline in patenting after controlling for research inputs. We then document a positive, significant, and fairly steady relationship between firms' patent and labor productivity growth rates. Average firm growth after controlling for patent growth, however, declines. Together, these results suggest that firms' innovative efforts play a key role in sustaining growth that has not diminished over the last four decades. |

| Abstract: | The increased emphasis on visual presentation and brand experience has elevated trade-dress from a peripheral concern to a central feature of trademark protection. Indian trade-dress protection is currently spread across multiple intellectual property legal regime with special emphasis through the passing-off law under the trademarks Act 1999. Despite commercial importance of trade-dress law, and without explicit statutory definition of what constitutes trade-dress, its protection is shaped almost entirely through a patchwork of judicial interpretation across the Supreme Court and the High Courts. The present study undertakes a mapping and comparative analysis of trade-dress jurisprudence across the Supreme Court of India and four major High Courts; Delhi, Bombay, Madras and Calcutta. The analysis reveals a fragmented landscape highlighting divergent judicial approaches to distinctiveness, consumer perception, functionality and evidentiary thresholds, The present study further identifies persistent doctrinal tensions from the conflation of trade-dress with copyright and design law in the Indian context. The authors argue for a more disciplined and coherent framework for trade-dress protection in India. |

| Abstract: | Innovation research frequently relies on patent data to study technological change, yet empirical coverage of cities in the Global South remains limited. Sequence analysis has gained increasing attention as a method for analysing categorical trajectories in social sciences, but its application to regional innovation studies is constrained by the lack of sequence-ready urban datasets. Moreover, integration of sequence analysis with network analysis is underexplored, despite its potential to jointly capture relational structures and trajectory patterns in innovation processes. This paper introduces a database of sequential patent data for the innovation trajectories of 4, 125 Global South cities. Derived from existing geocoded patent data, the database includes general and technology-specific datasets (computing, environmental technology, and medicine), each available in sequence, network, sequence–network, and panel formats. Spanning from 1980 to 2014 and covering cities from seven countries (Brazil, Chile, China, India, Mexico, South Africa, and Turkey), the database supports analyses of innovation dynamics and helps increase the representation of Global South cities in economic geography, development studies and innovation research. |
