Organizational Patent Count

While the previous chapter examined the system-level composition of patent assignees, the present chapter focuses on the individual organizations that underlie these aggregate patterns. The cumulative rankings, annual trajectories, and sequential transitions in leadership reveal how corporate patent strategies have evolved over five decades.

The rankings are dominated by technology firms and Asian corporations. Organizations such as Samsung, Canon, and LG have risen substantially since the 1990s, challenging the traditional dominance of US-based firms such as IBM and General Electric. Asian firms now account for over half of the top 25 patent holders.

Beyond utility patents, design patentsA patent granted for a new, original, and ornamental design for an article of manufacture. Protects appearance, not function. have become an increasingly important element of corporate intellectual property strategy. The organizations that lead in design patent filings are concentrated in consumer electronics, consumer brands, and fashion industries where product appearance is a key differentiator, a pattern consistent with the strategic importance of ornamental innovation in these sectors.

Not all patents are created equal. A small fraction of patents — so-called "blockbusters" — account for a disproportionate share of technological impact as measured by forward citations. Blockbuster patents are defined here as those in the top 1% of forward citations received within five years, normalized within each grant year and CPCCooperative Patent Classification — a hierarchical system jointly managed by the USPTO and EPO that categorizes patents by technology area (e.g., H = Electricity, G = Physics). section cohort. The Lorenz curve provides a natural way to visualize how evenly (or unevenly) these high-impact patents are distributed across organizations: if every firm produced blockbusters in exact proportion to its total patent output, the curve would follow the 45-degree line of perfect equality. Deviations below that line indicate concentration, and the associated Gini coefficient summarizes the degree of inequality in a single number.

Continuation and continuation-in-part filings allow applicants to extend patent families by filing related applications based on a parent filing. The share of patents that are continuations varies substantially across firms, reflecting differences in prosecution strategy, portfolio management, and the degree to which firms build incrementally on prior inventions.

The organizational patent count reveals a system in which leadership is dynamic and contested. IBM's cumulative dominance is narrowing as Samsung closes the gap, while design patent rankings add a distinct dimension where consumer-facing firms such as Nike and LG emerge alongside electronics giants. The structural concentration of patenting among elite organizations has remained stable at 31–39%, suggesting that scale-dependent barriers to large-volume patenting persist regardless of geography or technology era. Only 9 of 50 top filers have maintained their position across all five decades, underscoring how difficult it is for any single organization to remain at the frontier of technological change. The following chapter examines the citation quality and innovation impact of these leading firms in greater detail.
